China tightening controls on Internet






BEIJING (AP) — China‘s new communist leaders are increasing already tight controls on Internet use and electronic publishing following a spate of embarrassing online reports about official abuses.


The measures suggest China’s new leader, Xi Jinping, and others who took power in November share their predecessors’ anxiety about the Internet’s potential to spread opposition to one-party rule and their insistence on controlling information despite promises of more economic reforms.






“They are still very paranoid about the potentially destabilizing effect of the Internet,” said Willy Lam, a politics specialist at the Chinese University of Hong Kong. “They are on the point of losing a monopoly on information, but they still are very eager to control the dissemination of views.”


This week, China’s legislature took up a measure to require Internet users to register their real names, a move that would curtail the Web’s status as a freewheeling forum to complain, often anonymously, about corruption and official abuses. The legislature scheduled a news conference Friday to discuss the measure, suggesting it was expected to be approved.


That comes amid reports Beijing might be disrupting use of software that allows Web surfers to see sites abroad that are blocked by its extensive Internet filters. At the same time, regulators have proposed rules that would bar foreign companies from distributing books, news, music and other material online in China.


Beijing promotes Internet use for business and education but bans material deemed subversive or obscene and blocks access to foreign websites run by human rights and Tibet activists and some news outlets. Controls were tightened after social media played a role in protests that brought down governments in Egypt and Tunisia.


In a reminder of the Web’s role as a political forum, a group of 70 prominent Chinese scholars and lawyers circulated an online petition this week appealing for free speech, independent courts and for the ruling party to encourage private enterprise.


Xi and others on the party’s ruling seven-member Standing Committee have tried to promote an image of themselves as men of the people who care about China’s poor majority. They have promised to press ahead with market-oriented reforms and to support entrepreneurs but have given no sign of support for political reform.


Communist leaders who see the Internet as a source of economic growth and better-paid jobs were slow to enforce the same level of control they impose on movies, books and other media, apparently for fear of hurting fledgling entertainment, shopping and other online businesses.


Until recently, Web surfers could post comments online or on microblog services without leaving their names.


That gave ordinary Chinese a unique opportunity to express themselves to a public audience in a society where newspapers, television and other media are state-controlled. The most popular microblog services say they have more than 300 million users and some users have millions of followers reading their comments.


The Internet also has given the public an unusual opportunity to publicize accusations of official misconduct.


A local party official in China’s southwest was fired in November after scenes from a videotape of him having sex with a young woman spread quickly on the Internet. Screenshots were uploaded by a former journalist in Beijing, Zhu Ruifeng, to his Hong Kong website, an online clearing house for corruption allegations.


Some industry analysts suggest allowing Web surfers in a controlled setting to vent helps communist leaders stay abreast of public sentiment in their fast-changing society. Still, microblog services and online bulletin boards are required to employ censors to enforce content restrictions. Researchers say they delete millions of postings a day.


The government says the latest Internet regulation before the National People’s Congress is aimed at protecting Web surfers’ personal information and cracking down on abuses such as junk e-mail. It would require users to report their real names to Internet service and telecom providers.


The main ruling party newspaper, People’s Daily, has called in recent weeks for tighter Internet controls, saying rumors spread online have harmed the public. In one case, it said stories about a chemical plant explosion resulted in the deaths of four people in a car accident as they fled the area.


Proposed rules released this month by the General Administration of Press and Publications would bar Chinese-foreign joint ventures from publishing books, music, movies and other material online in China. Publishers would be required to locate their servers in China and have a Chinese citizen as their local legal representative.


That is in line with rules that already bar most foreign access to China’s media market, but the decision to group the restrictions together and publicize them might indicate official attitudes are hardening.


That comes after the party was rattled by foreign news reports about official wealth and misconduct.


In June, Bloomberg News reported that Xi’s extended family has amassed assets totaling $ 376 million, though it said none was traced to Xi. The government has blocked access to Bloomberg’s website since then.


In October, The New York Times reported that Premier Wen Jiabao’s relatives had amassed $ 2.7 billion since he rose to national office in 2002. Access to the Times’ Chinese-language site has been blocked since then.


Previous efforts to tighten controls have struggled with technical challenges in a country with more than 500 million Internet users.


Microblog operators such as Sina Corp. and Tencent Ltd. were ordered in late 2011 to confirm users’ names but have yet to finish the daunting task.


Web surfers can circumvent government filters by using virtual private networks — software that encrypts Web traffic and is used by companies to transfer financial data and other sensitive information. But VPN users say disruptions that began in 2011 are increasing, suggesting Chinese regulators are trying to block encrypted traffic.


Curbs on access to foreign sites have prompted complaints by companies and Chinese scientists and other researchers.


In July, the American Chamber of Commerce in China said 74 percent of companies that responded to a survey said unstable Internet access “impedes their ability to do business.”


Chinese leaders “realize there are detrimental impacts on business, especially foreign business, but they have counted the cost and think it is still worthwhile,” said Lam. “There is no compromise about the political imperative of controlling the Internet.”

Analysis: For tech investors, it’s hard to know when to bolt






(Reuters) – When Hewlett-Packard Co agreed to buy British software company Autonomy in August last year for $ 11.1 billion, two well-known investors made diametrically different bets on how the big deal would play out.


To short seller Jim Chanos, who had been raising red flags on Autonomy for years and had started shorting shares of HP in 2011, the deal was another nail in the coffin of the Silicon Valley tech giant, according to a source familiar with his thinking.






But to activist investor Ralph Whitworth, co-founder of Relational Investors LLC, it was time to commit to HP and the turnaround story the company was trying to sell to Wall Street. His fund bought more than 17.5 million HP shares after the deal was announced, and Whitworth received a seat on the company’s board. This year, Relational roughly doubled its stake in HP.


In the wake of HP’s decision to take an $ 8.8 billion write-down on the deal because of alleged accounting irregularities at Autonomy, it appears Chanos – whose call to short Enron before the energy company collapsed in a corporate scandal may be his most famous trade – was more astute.


HP’s shares are down 36 percent since Relational, which declined to comment, built its stake in the third quarter of 2011.


BARRIERS TO ENTRY


Relational’s big move into HP is a reminder that even smart investors can get things wrong in the fast-evolving technology sector, where once hot global names like Research in Motion and Yahoo can quickly become yesterday’s news.


It is a world where a company may effectively erect barriers to entry in a market only to have them torn down by a rival with a new whizz-bang product – just as Apple‘s iPhone broke the dominance that Research in Motion’s BlackBerry had enjoyed.


One warning sign that a tech company may be on the verge of losing its edge is when it makes acquisitions outside of its main area of expertise to move into new product lines. Savvy tech investors also say be wary of companies that experience a succession of management changes, or when a successful core business starts looking tired.


The pace of change in the technology sector is much faster than in other industries, said Kaushik Roy, an analyst at Hercules Technology Growth Capital. “It attracts new talent and capital, many startups are formed, which can be extremely disruptive to incumbents,” Roy said. “In other words, yesterday’s winners can rapidly become today’s losers and vice versa.”


In the case of HP, the company not only has had four CEOs since 1999, it has been striving to find another niche to dominate as demand for one of its core products – computer printers – wanes and as its PC business stumbles.


Or consider online search pioneer Yahoo, which has gone through six chief executives and is struggling to keep pace with Google.


Josh Spencer, a portfolio manager at T. Rowe Price, said frequent turnover in the executive suite at Yahoo was a warning sign to him. Spencer said he does not own Yahoo shares and has not in the recent past.


RED FLAGS


While a company may view an acquisition as a fresh start – that is what HP was trying to say about Autonomy – some investors see it as a warning the core business is struggling.


Spencer noted that the technology industry’s most successful companies – Apple and Samsung – generally have not made acquisitions and instead developed new products internally.


For Margaret Patel, managing director at Wells Capital Management, one of the first red flags she saw at HP was when former CEO Carly Fiorina bought Compaq for roughly $ 25 billion in 2002.


“I felt then that the acquisition was too large and expensive, and personal computers were not their core strength,” said Patel, who has since avoided investing in HP.


Of course, timing can be everything even if an investor is eventually proven right. Patel missed out on a 137 percent gain in HP’s stock price from the time of the Compaq deal up until the end of 2010.


PREMIUM VALUATIONS


A few money managers see a flashing yellow light in the big sell-off of Apple shares in the past few months.


Apple, the most valuable U.S. company, has shed nearly 30 percent of its value in the last three months.


Since the death of co-founder Steve Jobs – the driving force behind Apple’s iPod, iPhone and iPad – DoubleLine co-founder Jeffrey Gundlach has been recommending that investors short the company’s shares because “the product innovator isn’t there anymore.”


Gundlach said he began shorting Apple’s stock at around $ 610 and maintains that it could drop to $ 425. He declined to comment on Tim Cook, who succeeded Jobs over a year ago and is seen by many as less visionary and innovative than Jobs.


Christian Bertelsen, chief investment officer at Global Financial Private Capital, with assets under management of $ 1.7 billion, said his firm began paring back its exposure to Apple this fall because he felt the expectations for the company’s new iPhone5 had gotten overheated.


He said his firm dramatically took down its exposure to Apple shares when the stock hit $ 670 a share. “For us, the light bulb went off this fall,” he said. Mind you, Apple’s shares still remain up about 25 percent for the whole year.


And then there’s Research in Motion. Once a leader in smartphones, it’s now in danger of becoming irrelevant.


“They saw the move towards all touch-screen phones and didn’t move with it,” said Stuart Jeffrey, an analyst at Nomura Securities who noted how the BlackBerry 10 touch-screen phone will debut on January 30, 2013, six years after Apple released its first iPhone in 2007.


Robert Stimpson, a portfolio manager at Oak Associates Funds whose fund does not own any shares of Research in Motion, said the company’s BlackBerry phones are on a downward slope and it will be tough for the company to regain its lost luster.


“The end of the road is a long, lonely journey,” Stimpson said of Research in Motion. “I think they will fight the good fight for many years, probably unsuccessfully.”

Police investigate NBC News anchor for showing gun clip






(Reuters) – NBC News anchor David Gregory is being investigated by police after displaying what he said was a high-capacity gun clip on Sunday’s broadcast of “Meet the Press,” Washington‘s Metropolitan Police Department said Wednesday.


Gregory held up what appeared to be a 30-round gun magazine – which would be barred under Washington municipal code – while hosting the nationally broadcast interview with National Rifle Association Chief Executive Officer Wayne LaPierre.






“Here is a magazine for ammunition that carries 30 bullets,” Gregory said as he held aloft the black cartridge, according to video posted on the network’s website.


“Now isn’t it possible that, if we got rid of these, if we replaced them and said ‘Well, you could only have a magazine that carries five bullets or ten bullets,’ isn’t it just possible that we can reduce the carnage in a situation like Newtown?” Gregory asked LaPierre.


“I don’t think it’s what will work,” LaPierre responded.


The network had contacted the police department prior to Sunday’s broadcast “inquiring if they could use a high capacity magazine for the segment,” police spokesman Araz Alali said on Wednesday.


NBC was informed that possession of a high-capacity magazine was not permissible and their request was denied.”


Alali, the police spokesman, declined to elaborate on the investigation into NBC.


Washington’s municipal code prohibits possession, sale or transfer of “any large capacity ammunition feeding device, regardless of whether the device is attached to a firearm.”


The maximum penalty for conviction on such a charge is a $ 1,000 fine and one year in prison.


NBC spokeswoman Erika Masonhall, contacted by email, said the network had no comment on the investigation.


After the broadcast, which originated in Washington, a number of bloggers and websites questioned Gregory’s actions and the legality of the gun clip.

Mayo Scientists Link Enzyme to Aggressive Prostate Cancer






Researchers from the Mayo Clinic have directly linked an enzyme to aggressive prostate cancer. They’ve also developed a compound that restricts the ability of the molecule to fuel metastases of this type of cancer.


The team from Mayo’s Florida campus identified the first direct relationship between the enzyme known as PRSS3 to prostate cancer, according to Medical News Today. They published their results in Molecular Cancer Research.






The National Cancer Institute estimated that close to a quarter of a million men would be diagnosed with prostate cancer in 2012, and around 28,000 of them wouldn’t survive.


For years, medical professionals have relied on two types of screening for this disease: a digital rectal exam and the prostate specific antigen (PSA) test. However, the Mayo Clinic says using the PSA test is sometimes controversial, since it can provide false indicators and since there is no proof that it actually saves lives.


PRSS3, a protease, digests other molecules. The Mayo researchers concluded that activity associated with the enzyme alters the environment surrounding prostate cancer cells. They suspect that PRSS3 frees the cells from surrounding tissue, allowing them to become invasive and to spread cancer.


They haven’t concluded that the enzyme is the only issue linked to aggressive prostate cancer, however. Instead, they suspect that PRSS3 might power a potentially lethal form of this cancer.


The researchers examined databases available to the public that contained information from clinical studies. After finding a link between early breast cancer and protease in earlier work, they sought to discover whether any other type of cancer expressed protease and at which stages of the disease.


They found a dramatic relationship between increases in PRSS3 expression and progression of aggressive prostate cancer. The scientists determined that protease expression played a critical role in prostate cancer metastasis in mice models and found a site for an inhibiting agent to shut down the expression. In mice in which PRSS3 was “shut off,” the malignancy did not spread.


One outcome of the study is the possibility of testing prostate cancer patients for the molecule. Doctors could better determine patients at highest risk for an aggressive form of the disease. While the inhibitor utilized cannot be directly developed into a useful drug, it could provide a template for creating one.


My husband is among those who could eventually profit from this study. After two successive PSA tests with numbers that suddenly skyrocketed, he underwent painful biopsies that showed nothing amiss. Although his PSA numbers bounce, his urologist insists that he keep repeating the test.


With a family history of aggressive prostate cancer, my husband finds it hard to argue. Should he nix more PSA tests and eventually develop the illness, the link between the enzyme and prostate cancer provides some hope of a positive outcome.

Home prices rose in ninth straight month: S&P






NEW YORK (Reuters) – Single-family home prices rose in October for nine months in a row, reinforcing the view the domestic real estate market is improving and should bolster the economy in 2013, a closely watched survey showed on Wednesday.


The S&P/Case Shiller composite index of 20 metropolitan areas gained 0.7 percent in October on a seasonally adjusted basis, stronger than the 0.5 percent rise forecast by economists polled by Reuters.






“Looking over this report, and considering other data on housing starts and sales, it is clear that the housing recovery is gathering strength,” David Blitzer, chairman of the index committee at Standard & Poor’s, said in a statement.


While record low mortgage rates and modest job growth should keep the housing recovery on track, analysts cautioned home prices face downward pressure from a likely pickup in the sales of foreclosed and distressed properties and reduced buying investors and speculators.


Prices in the 20 cities rose 4.3 percent year over year, beating expectations for a rise of 4.0 percent.


Las Vegas posted the biggest monthly rise on a seasonally adjusted basis at 2.4 percent, followed by a 1.7 percent increase in San Diego, the latest Case-Shiller data showed.


“Higher year-over-year price gains plus strong performances in the Southwest and California, regions that suffered during the housing bust, confirm that housing is now contributing to the economy,” Blitzer said.


Housing contributed 10 percent to the overall U.S. economic growth in the third quarter, while the sector represented less than 3 percent of gross domestic product, he said.


Last week, the government said U.S. GDP expanded at a stronger-than-expected 3.1 percent annualized pace in the third quarter.


Excluding seasonal factors, however, home prices in 12 of the 20 cities fell in October from September as home values tend to decline in fall and winter, Blitzer said.


Chicago experienced the largest non-seasonally adjusted decline at 1.5 percent, followed by a 1.4 percent fall in Boston.

Afghan bomber attacks near major US base






KABUL, Afghanistan (AP) — A vehicle driven by a suicide bomber exploded at the gate of a major U.S. military base in eastern Afghanistan on Wednesday, killing the attacker and three Afghans, Afghan police said. The Taliban claimed responsibility for the attack.


Police Gen. Abdul Qayum Baqizai said a local guard who questioned the vehicle driver at the gate of Camp Chapman was killed along with two civilians and the assailant. The camp is located adjacent to the airport of the capital of Khost province, which borders Pakistan. Chapman and nearby Camp Salerno had been frequently targeted by militants in the past, but violent incidents have decreased considerably in recent months.






Taliban spokesman Zabihullah Mujahid said in an email that the bomber targeted Afghan police manning the gate and Afghans working for the Americans entering the base. He claimed high casualties were inflicted.


NATO operates with more than 100,000 troops in the country, including some 66,000 American forces. It is handing most combat operations over to the Afghans in preparation for a pullout from Afghanistan in 2014. Militant groups, including the Taliban, rarely face NATO troops head-on and rely mainly on roadside bombs and suicide attacks.


NATO forces and foreign civilians have also been increasingly attacked by rogue Afghan military and police, eroding trust between the allies.


On Tuesday, the Interior Ministry said a policewoman who killed an American contractor in Kabul a day earlier was a native Iranian who came to Afghanistan and displayed “unstable behavior” but had no known links to militants.


The policewoman, identified as Sgt. Nargas, shot 49-year-old Joseph Griffin, of Mansfield, Georgia, on Monday, in the first such shooting by a woman in the spate of insider attacks. Nargas walked into a heavily-guarded compound in the heart of Kabul, confronted Griffin and shot him once with her pistol.


The U.S-based security firm DynCorp International said on its website that Griffin was a U.S. military veteran who earlier worked with law enforcement agencies in the United States. In Kabul, he was under contract to the NATO military command to advise the Afghan police force.


The ministry spokesman, Sediq Sediqi, told a news conference that Nargas, who uses one name like many in the country, was born in Tehran, where she married an Afghan. She moved to the country 10 years ago, after her husband obtained fake documents enabling her to live and work there.


A mother of four in her early 30s, she joined the police five years ago, held various positions and had a clean record, he said. Sediqi produced an Iranian passport that he said was found at her home.


No militant group has claimed responsibility for the killing.


The chief investigator of the case, Police Gen. Mohammad Zahir, said that during interrogation, the policewoman said she had plans to kill either the Kabul governor, city police chief or Zahir himself, but when she realized that penetrating the last security cordons to reach them would be too difficult, she saw “a foreigner” and turned her weapon on him.


There have been 60 insider attacks this year against foreign military and civilian personnel, compared to 21 in 2011. This surge presents another looming security issue as NATO prepares to pull out almost all of its forces by 2014, putting the war against the Taliban and other militant groups largely in the hands of the Afghans.


More than 50 Afghan members of the government’s security forces also have died this year in attacks by their own colleagues. The Taliban claims such incidents reflect a growing popular opposition to the foreign military presence and the Kabul government.

Nokia Lumia 920′s fascinating Christmas sets stage for battle with BlackBerry 10






The Chinese version of Nokia’s (NOK) new flagship Windows Phone model recently debuted in Shanghai. According to pictures posted to Chinese websites, the Lumia 920T drew a big crowd… and sold out in two hours. So the debate over whether there is wide mass market demand for the model rages on.


[More from BGR: Microsoft Surface trampled at the bottom of the tablet pile this Christmas]






The very limited early supply makes it hard to gauge the demand in China. The Lumia 920 did hit Amazon China’s (AMZN) top-five list a week ago, but sold out quickly and dropped out. There are now rumors about China Mobile planning to further subsidize the Lumia 920T in January, making it effectively free on contract. This would be China Mobile’s revenge on Apple (AAPL) for its refusal to cut a sweetheart deal with the giant carrier and its 700 million subscribers.


[More from BGR: Purported photo of new BlackBerry phone with QWERTY keyboard leaks]


Nokia may thus be close to landing the Chinese version of the role that Motorola played for Verizon (VZ) in 2010. Back then, the U.S. carrier used DROID models to flaunt the fact that it did not really need the iPhone as badly as many assumed.


China Mobile is now planning to show Apple it can turn even Windows Phones into mass-market hits in China with its marketing and subsidy machine. This could be great for Nokia — if Apple isn’t forced into a cutting a quick deal in coming months. The iPhone’s ho-hum market share performance in markets like Latin America and Asia is piling pressure on Apple right about now.


In a fascinating U.S. twist, the Lumia 920 climbed the Amazon charts again over the past week as its supply has improved. The black variant of the Lumia 920 debuted in the top-three in November, dropped out of top-40 after Amazon’s delivery time stretched to two weeks… and has now staged a comeback to No.14. This makes it the second-biggest AT&T (T) phone on Amazon right now, with only the blue version of the Galaxy S III outperforming the 920.


The Lumia 822 is fizzling badly at Verizon, but Nokia just might be gaining a toehold at AT&T even after the pre-Christmas supply drama. It is now clear that the Lumia 920 is beating its biggest Windows rival, the HTC Windows Phone 8X, convincingly at AT&T.


This sets up a very interesting rivalry when AT&T debuts the new generation of BlackBerry 10 models sometime in February or March. The battle for the third mobile ecosystem at AT&T will be effectively waged by Nokia and RIM (RIMM) this spring. The loser may well find out that it does not have strong subsidy or marketing support in 2013.


AT&T has an incentive to build up a third rival for the Apple and Android ecosystems, but it has little reason to support both minor operating systems.

Jessica Simpson’s Christmas gift: She’s pregnant






NEW YORK (AP) — Jessica Simpson‘s daughter has the news all spelled out: “Big Sis.”


Simpson on Tuesday tweeted a photo of her baby daughter Maxwell playing in the sand, the words “Big Sis” spelled out.






The 32-year-old old singer and personality has been rumored to be expecting again. The tweet appears to confirm the rumors.


“Merry Christmas from my family to yours” is the picture’s caption. Simpson used a tweet on Halloween in 2011 to announce she was pregnant with Maxwell. She is engaged to Eric Johnson and gave birth to Maxwell in May.


One possible complication regarding her pregnancy: She is a spokeswoman for Weight Watchers.

Link between pot, psychosis goes both ways in kids






NEW YORK (Reuters Health) – Marijuana (cannabis) use may be linked to the development of psychotic symptoms in teens – but the reverse could also be true: psychosis in adolescents may be linked to later pot use, according to a new Dutch study.


“We have focused mainly on temporal order; is it the chicken or the egg? As the study shows, it is a bidirectional relationship,” wrote the study’s lead author Merel Griffith-Lendering, a doctoral candidate at Leiden University in The Netherlands, in an email to Reuters Health.






Previous research established links between marijuana and psychosis, but scientists questioned whether pot use increased the risk of mental illness, or whether people were using pot to ease their psychotic symptoms, such as hallucinations and delusions.


“What is interesting in this study is that both processes are going on at the same time,” said Dr. Gregory Seeger, medical director for addiction services at Rochester General Hospital in upstate New York.


He told Reuters Health that researchers have been especially concerned about what tetrahydrocannabinol (THC), the active property in pot, could do to a teenager’s growing brain.


“That’s a very vulnerable period of time for brain development,” and individuals with a family history of schizophrenia and psychosis seem to be more sensitive to the toxic effects of THC, he said.


A 2010 study of 3,800 Australian teenagers found that those who used marijuana were twice as likely to develop psychosis compared to teens who never smoked pot (see Reuters Health article of March 1, 2010 here:).


But that study also found that those who suffered from hallucinations and delusions when they were younger were also more likely to use pot early on.


CHICKEN v. EGG


For the new study, published in the journal Addiction, the researchers wanted to see which came first: pot or psychosis.


Griffith-Lendering and her colleagues used information on 2,120 Dutch teenagers, who were surveyed about their pot use when they were about 14, 16 and 19 years old.


The teens also took psychosis vulnerability tests that asked – among other things – about their ability to concentrate, their feelings of loneliness and whether they see things other people don’t.


Overall, the researchers found 940 teens, or about 44 percent, reported smoking pot, and there was a bidirectional link between pot use and psychosis.


For example, using pot at 16 years old was linked to psychotic symptoms three years later, and psychotic symptoms at age 16 were linked to pot use at age 19.


This was true even when the researchers accounted for mental illness in the kids’ families, alcohol use and tobacco use.


Griffith-Lendering said she could not say how much more likely young pot users were to exhibit psychotic symptoms later on.


Also, the new study cannot prove one causes the other. Genetics may also explain the link between pot use and psychosis, said Griffith-Lendering.


“We can say for some people that cannabis comes first and psychosis comes second, but for some people they have some (undiagnosed) psychosis (and) perhaps cannabis makes them feel better,” said Dr. Marta Di Forti, of King’s College, London, who was not involved with the new research.


Di Forti, who has studied the link between pot and psychosis, told Reuters Health she considers pot a risk factor for psychosis – not a cause.


Seeger, who was also not involved with the new study, said that there needs to be more public awareness of the connection.


“I think the marijuana is not a harmless substance. Especially for teenagers, there should be more of a public health message out there that marijuana has a public health risk,” he said.


Griffith-Lendering agrees.


“Given the severity and impact of psychotic disorders, prevention programs should take this information into consideration,” she said.

Taking on Guns and the NRA, One Tweet at a Time






(Updates the number of video views, petition signatures, and twitter impressions)


On Dec. 21, a group of A-list Hollywood celebrities, including Jon Hamm, Reese Witherspoon, Jamie Foxx, and Beyoncé, posted an 80-second, black-and-white video clip on YouTube calling for lawmakers to develop a comprehensive plan to deal with gun violence. The clip, uploaded the same day the National Rifle Association held a press conference calling for armed guards in schools and no new restrictions on guns, has been viewed 4 million times.






The public service announcement is well-produced and hits all the intended emotional chords as it reminds viewers of mass shootings from Columbine to Newtown. It’s is part of a broader “Demand a Plan” social media campaign by the advocacy group Mayors Against Illegal Guns that was launched right after the Newtown massacre. (The group is co-chaired by New York Mayor Michael Bloomberg, founder of Bloomberg L.P., which owns Bloomberg Businessweek.) The video also raises an intriguing question: Can social media strategies somehow level the playing field with the NRA, a laser-focused, well-financed, and successful lobbying group with four million members?


John Feinblatt, who oversees MAIG and is a chief policy adviser to the mayor, is ready to go on the offensive with the NRA and thinks the moment has arrived for the gun safety movement  to make legislative advances. He says there is “enormous pent up frustration because Americans want to be safe.” Facebook (FB), Twitter, and YouTube (GOOG) can effectively focus that raw energy on Congress and President Barack Obama to get things moving and undercut the NRA’s clout in Washington. “What people want is to be heard and you have to give them that vehicle,” says Feinblatt.


The Demand a Plan site delivers that video testimonials of 30-plus survivors and victims’ family members and all manner of online tools to mobilize support and donations to pressure the White House and Congress. Some 600,000 users have signed an online petition to ban assault weapons and high capacity magazines, require criminal background checks on every gun sold in the U.S., and crack down on arms trafficking. The Demand a Plan campaign has generated 10 million tweet impressions since its launch on Dec. 17, according to Feinblatt. This chart of Google search results for “gun control” shows interest spiking far higher after Newtown, compared with responses to other shooting incidents, going back to 2005.


Yet it’s worth asking if a “Twitter Revolution,” to borrow from the Arab Spring lexicon, can change the U.S. gun policy debate over the long haul? Social media is a great technology for disseminating information, organizing protests, and expressing spontaneous emotion—but it is unclear how effective it might be in a prolonged legislative battle to sway, cajole, and basically electorally threaten lawmakers beholden to the NRA and gun industry money.


“Signing an online petition is easy, but getting the continuing electoral and financial support of millions is difficult,” says Harry Wilson,  a gun industry expert and a public policy professor at Roanoke College in Virginia. “If gun control groups, including MAIG, are not significantly emboldened and empowered by the Newtown tragedy, then they have lost the battle.”
