Let the debate end: Grammy noms anybody's guess

NASHVILLE, Tenn. (AP) — It's a brutal year to be in the Grammy nominations handicapping game.

Sure, there are a few safe bets. Mumford & Sons and Frank Ocean are expected to take a share of nominations when they're announced Wednesday night on national television during "The Grammy Nominations Concert Live!" in Nashville.

And popular songs by Gotye, fun., Taylor Swift and Carly Rae Jepsen may land those artists on the list as well, though Jepsen harbors some doubt her omnipresent song "Call Me Maybe" will net a nod.

"I would be so shocked," the 27-year-old singer said last week. "But this year has taught me to look forward to surprises and just be ready for anything. So, cross your fingers for me."

Viral songs like Jepsen's seemed to be the theme of the year, and with no watershed albums during the nominating period for the 2013 Grammys like Adele's "21" or Kanye West's "My Beautiful Dark Twisted Fantasy," it's not clear who will turn out as this year's top nominee.

Thus the guessing game.

The Grammy nominations period ended Sept. 30 and three of the year's top four debuting albums — from Swift, One Direction and Jason Aldean — came after that date. Rihanna also released a new album after the period ended. All could have songs nominated, but a popular album is the quickest way to accumulate multiple nods.

Mumford & Sons slipped in just under the deadline. Introduced to much of their burgeoning fan base through a 2011 appearance on the Grammys, the British folk-rock band could return with a flourish after selling 600,000 copies of "Babel" in the first week of release and setting streaming records on Spotify.

And Ocean showed the kind of bravery that might be rewarded by The Recording Academy's voters when he announced in liner notes for his album "channel ORANGE" that he'd had a same-sex encounter, causing an industry-wide discussion of the issue.

Questions surround many of the other artists who might be considered sure bets, however. Gotye should be a lock in multiple categories, but his viral song "Somebody That I Used to Know," featuring Kimbra, wasn't submitted in the song of the year category because of a sample, eliminating one of its most viable prospects.

Others who might be considered possible top nominees like Drake and The Black Keys released their platinum-selling, hit-spawning albums late last year and they'll have to overcome short-term memory issues among voters.

Sean Garrett, a producer for artists like Usher and Beyonce with multiple Grammy nominations, said a lack of clear trends during the nominating period made it difficult to guess going into the show.

"It was sort of an iffy kind of year in my opinion," Garrett said in a phone interview. "I'm going to be honest: I think the politics kind of slowed the music down."

He expects pop stars like Jepsen, Bieber, Swift and Korean sensation PSY to take home nominations, but doesn't see an artist accumulating a high number of nominations. That could leave room for newer acts, including fun., one of his favorites.

"They have a very clever sound," Garrett said. "The lead singer (Nate Reuss) has an amazing, amazing voice. I feel like they just came with something that was a bit different. It was mainstream pop music and it had some edge to it. And there was great songwriting there."

Fun., with their anthemic hit "We Are Young," are among the night's performers, joining Maroon 5, Ne-Yo, Luke Bryan, The Who, Hunter Hayes and others.

"It just feels like we spent the last 12 years pulling back the arrow and this year we just let it go," fun. guitarist Jack Antonoff said. "This last year has been incredible and amazing and hard and I don't even know what it would have been like if we didn't have 10 or 12 years of experience because it still feels like we're learning everything for the first time."

The nominations show is being held outside Los Angeles for the first time in its five-year history. LL Cool J returns, co-hosting the show live on CBS at 10 p.m. EST from Bridgestone Arena with Swift.

It's the first official Grammy activity in Music City since 1973, when the late Johnny Cash kicked off the live broadcast. He'll figure into Wednesday night's as well when Dierks Bentley and The Band Perry pay tribute to the man in black.

"So we're going to do that as a tribute to Johnny, a tribute to Nashville, a tribute to country music, a tribute to being back here," longtime Grammy producer Ken Ehrlich said. "And I think it will be magical."

Extended Use of Breast Cancer Drug Suggested

The widely prescribed drug tamoxifen already plays a major role in reducing the risk of death from breast cancer. But a new study suggests that women should be taking the drug for twice as long as is now customary, a finding that could upend the standard that has been in place for about 15 years.

In the study, patients who continued taking tamoxifen for 10 years were less likely to have the cancer come back or to die from the disease than women who took the drug for only five years, the current standard of care.

“Certainly, the advice to stop in five years should not stand,” said Prof. Richard Peto, a medical statistician at Oxford University and senior author of the study, which was published in The Lancet on Wednesday and presented at the San Antonio Breast Cancer Symposium.

Breast cancer specialists not involved in the study said the results could have the biggest impact on premenopausal women, who account for a fifth to a quarter of new breast cancer cases. Postmenopausal women tend to take different drugs, but some experts said the results suggest that those drugs as well might be taken for a longer duration.

“We’ve been waiting for this result,” said Dr. Robert W. Carlson, a professor of medicine at Stanford University. “I think it is especially practice-changing in premenopausal women because the results do favor a 10-year regimen.”

Dr. Eric P. Winer, chief of women’s cancers at the Dana-Farber Cancer Institute in Boston, said that even women who completed their five years of tamoxifen months or years ago might consider starting on the drug again.

Tamoxifen blocks the effect of the hormone estrogen, which fuels tumor growth in estrogen receptor-positive cancers that account for about 65 percent of cases in premenopausal women. Some small studies in the 1990s suggested that there was no benefit to using tamoxifen longer than five years, so that has been the standard.

About 227,000 cases of breast cancer are diagnosed each year in the United States, and an estimated 30,000 of them would be in premenopausal women with ER-positive cancer and prime candidates for tamoxifen. But postmenopausal women also take tamoxifen if they cannot tolerate the alternative drugs, known as aromatase inhibitors.

The new study, known as Atlas, included nearly 7,000 women with ER-positive disease who had completed five years of tamoxifen. They came from about three dozen countries. Half were chosen at random to take the drug another five years, while the others were told to stop.

In the group assigned to take tamoxifen for 10 years, 21.4 percent had a recurrence of breast cancer in the ensuing ten years, meaning the period 5 to 14 years after their diagnoses. The recurrence rate for those who took only five years of tamoxifen was 25.1 percent.

About 12.2 percent of those in the 10-year treatment group died from breast cancer, compared with 15 percent for those in the control group.

There was virtually no difference in death and recurrence between the two groups during the five years of extra tamoxifen. The difference came in later years, suggesting that tamoxifen has a carry-over effect that lasts long after women stop taking it.

Whether these differences are big enough to cause women to take the drug for twice as long remains to be seen.

“The treatment effect is real, but it’s modest,” said Dr. Paul E. Goss, director of breast cancer research at the Massachusetts General Hospital.

Tamoxifen has side effects, including endometrial cancer, blood clots and hot flashes, which cause many women to stop taking the drug. In the Atlas trial, it appears that roughly 40 percent of the patients assigned to take tamoxifen for the additional five years stopped prematurely.

Some 3.1 percent of those taking the extra five years of tamoxifen got endometrial cancer versus 1.6 percent in the control group. However, only 0.6 percent of those in the longer treatment group died from endometrial cancer or pulmonary blood clots, compared with 0.4 percent in the control group.

“Over all, the benefits of extended tamoxifen seemed to outweigh the risks substantially,” Trevor J. Powles of the Cancer Center London, said in a commentary published by The Lancet.

Dr. Judy E. Garber, director of the Center for Cancer Genetics and Prevention at Dana-Farber, said many women have a love-hate relationship with hormone therapies.

DealBook: Freeport to Buy Plains Exploration and McMoRan

Freeport-McMoRan Copper and Gold said on Wednesday that it would buy two oil and natural gas companies, Plains Exploration and Production and the McMoRan Exploration Company, in a return to the energy business.

The two transactions will create a natural resources titan worth about $60 billion, including debt, and will formally reunite Freeport with McMoRan, the oil exploration company it spun off in 1994.

Under the terms of the deals, Freeport will pay about $6.9 billion in cash and stock for Plains. That offer consists of $25 a share in cash and 0.6531 of a Freeport share, worth about $50 a share based on Tuesday’s closing prices.

And Freeport will pay $14.75 a share in cash and 1.15 units of a trust that will hold a 5 percent interest in future production of McMoRan’s deepwater exploration operations. Freeport and Plains together already own about 36 percent of the smaller exploration company.

“This transaction will enable us to add assets with exceptional exploration and development potential to a world-class mining company to create a premier minerals and oil and gas business focused on value creation for shareholders,” James R. Moffett, Freeport’s chairman, said in a statement.

JPMorgan Chase is providing $9.5 billion to help pay for the cash portion of the deal and to repay some of Plains’s existing debt.

Freeport was advised by Credit Suisse and the law firm Wachtell, Lipton, Rosen & Katz. Plains was advised by Barclays and the law firm Latham & Watkins. McMoRan was advised by Evercore Partners and the law firm Weil, Gotshal & Manges.

Pakistan’s Hazara Shiites Under Siege

Declan Walsh/The New York Times

Many members of the Hazara Shiite community killed by Sunni extremists are buried in a graveyard in Quetta, Pakistan.

QUETTA, Pakistan — Calligraphers linger at the gates of an ancient graveyard in this brooding city in western Pakistan, charged with a macabre and increasingly in-demand task: inscribing the tombstones of the latest victims of the sectarian death squads that openly roam these streets.

For at least a year now, Sunni extremist gunmen have been methodically attacking members of the Hazara community, a Persian-speaking Shiite minority that emigrated here from Afghanistan more than a century ago. The killers strike with chilling abandon, apparently fearless of the law: shop owners are gunned down at their counters, students as they play cricket, pilgrims dragged from buses and executed on the roadside.

The latest victim, a mechanic named Hussain Ali, was killed Wednesday, shot inside his workshop. He joined the list of more than 100 Hazaras who have been killed this year, many in broad daylight. As often as not, the gunmen do not even bother to cover their faces.

The bloodshed is part of a wider surge in sectarian violence across Pakistan in which at least 375 Shiites have died this year — the worst toll since the 1990s, human rights workers say. But as their graveyard fills, Hazaras say the mystery lies not in the identity of their attackers, who are well known, but in a simpler question: why the Pakistani state cannot — or will not — protect them.

“After every killing, there are no arrests,” said Muzaffar Ali Changezi, a retired Hazara engineer. “So if the government is not supporting these killers, it must be at least protecting them. That’s the only way to explain how they operate so openly.”

The government, already battling Taliban insurgents, insists it is taking the threat seriously. During the recent Mourning of Muhurram, when Shiites parade through the streets over 10 days, the Interior Ministry imposed stringent security measures such as blocking cellphone signals for up to 12 hours — to try to prevent remote bomb detonations — and banning doubled-up motorcycle riding. Even so, Sunni bombers struck at least five times, killing at least 50 Shiites and wounding several hundred. The Pakistani Taliban claimed responsibility for the biggest attacks, highlighting an emerging link between that group and traditional sectarian militants that has worried many.

Yet the unchecked killings have also raised wider questions about Pakistani society: about the spread of a cancerous sectarian ideology in a public that even just a decade ago seemed more tolerant, and about what might be spurring the growing audacity of the killers, some of whom are believed to have links to the country’s security services.

The murders in Quetta, for instance, involve remarkably little mystery. By wide consensus, the gunmen are based in Mastung, a dusty agricultural village 18 miles to the south that is the bustling local hub of Lashkar-e-Jhangvi, the country’s most notorious sectarian militant group.

Like so many Pakistani groups that combine guns with zealotry, Lashkar-e-Jhangvi thrives in a wink-and-nod netherworld: it is officially banned, but its leader, Malik Ishaq, was released from jail last year amid showers of rose petals thrown by supporters. Now Mr. Malik lives openly in southern Punjab Province, protected by armed men who loiter outside his door, allowing him to deliver hate-laced statements to visitors. Shiites are “the greatest infidels on earth,” he told a Reuters reporter last month.

In Quetta, his followers are similarly unfettered. In targeting the Hazara — who, with their distinctive Central Asian features, are easy to pick out — Lashkar-e-Jhangvi militants block busy highways as they search vehicles for Hazaras and daub walls with hate slogans. “The face is the target,” said Major Nadir Ali, a senior Hazara leader and retired army officer. “They see the face, then they shoot.”

Fleetwood Mac readies tour and new music

NEW YORK (AP) — Fleetwood Mac is heading back on the road, and that means the top-selling group will release new music — sort of.

On its 34-city North American tour, which kicks off April 4 in Columbus, Ohio, the band will perform two new songs, and it could mean a new album will follow. Or not.

Stevie Nicks recently sang on tracks that Lindsey Buckingham, Mick Fleetwood and John McVie worked on, calling the sessions "great." But Nicks also says she's not sure where the band fits in today's music industry.

"Whether or not we're gonna do any more (songs), we don't know because we're so completely bummed out with the state of the music industry and the fact that nobody even wants a full record," she said. "Everybody wants two songs, so we're going to give them two songs."

Nicks said depending on the response to the new tracks — which Buckingham calls "the most Fleetwood Mac-y stuff ... in a long time" — more material could come next.

"Maybe we'll get an EP out of it or something," Buckingham said.

Nicks will continue to record solo albums, though. The group is celebrating the 35th anniversary of the best-selling "Rumours" album, which has moved some 20 million units in the United States. She knows that's not possible again, despite the success of Adele's "21," which has sold 10 million units in America in less than two years.

"This is Adele's 'Rumours,'" Nicks said. "She had a baby, she's going to take a year off to take care of her baby — that's why I never had any kids. She's going to go back and start writing again, you never know what the next record's going to be. Is it going to sell 10 million records? You don't know," she said.

Buckingham said he initially wanted to record a new album, but Nicks "wasn't too into that." But the guitarist and singer knows that new music isn't a priority for the band's fans.

"It wouldn't matter if they didn't hear anything new. In a way there's a freedom to that — it becomes not what you got, but what you do with what you got. Part of the challenge of this tour is figuring out a presentation that has some twists and turns to it without having a full album," he said.

Fleetwood Mac, which was formed in 1967, last released an album in 2003, though they hit the road in 2009. Nicks and Buckingham — who originally joined the band in 1974 as a couple — both released solo albums and toured last year. Buckingham had suggested that Fleetwood Mac tour last year, but says getting everyone to agree was tough.

"If you look at Fleetwood Mac as a group, you can make the case of saying we're a bunch of individuals who don't necessarily belong in the same group together, but it's the synergy of that that makes us so good. But it also makes the politics a little more tenuous," he said. "You can say that not only can it be a political minefield, someone's always causing trouble, right? I caused trouble for years so I can't point any fingers."

The tour also includes cities such as New York, Chicago, Boston, Las Vegas and Los Angeles, and will end June 12 in Detroit.

National Briefing | New England: New Hampshire: Not Guilty Plea in Hepatitis Case

A traveling hospital technologist accused of stealing drugs and infecting patients with hepatitis C through contaminated syringes pleaded not guilty in federal court on Monday. The technologist, David Kwiatkowski, whom prosecutors described as a “serial infector,” was indicted last week on charges of tampering with a consumer product and illegally obtaining drugs. Until May, Mr. Kwiatkowski worked as a cardiac technologist at Exeter Hospital, where 32 patients were given diagnoses of the same strain of hepatitis C he carries. Before that, he worked in 18 hospitals in seven states, moving from job to job despite having been fired twice over accusations of drug use and theft. In addition to the New Hampshire patients, a handful of patients in Kansas and one in Maryland have been found to carry the strain Mr. Kwiatkowski carries.

Generic Drug Makers Facing Squeeze on Revenue

They call it the patent cliff.

Brand-name drug makers have feared it for years. And now the makers of generic drugs fear it, too.

This year, more than 40 brand-name drugs — valued at $35 billion in annual sales — lost their patent protection, meaning that generic companies were permitted to make their own lower-priced versions of well-known drugs like Plavix, Lexapro and Seroquel — and share in the profits that had exclusively belonged to the brands.

Next year, the value of drugs scheduled to lose their patents and be sold as generics is expected to decline by more than half, to about $17 billion, according to an analysis by Crédit Agricole Securities.“The patent cliff is over,” said Kim Vukhac, an analyst for Crédit Agricole. “That’s great for large pharma, but that also means the opportunities theoretically have dried up for generics.”

In response, many generic drug makers are scrambling to redefine themselves, whether by specializing in hard-to-make drugs, selling branded products or making large acquisitions. The large generics company Watson acquired a European competitor, Actavis, in October, vaulting it from the fifth- to the third-largest generic drug maker worldwide.

“They are certainly saying either I need to get bigger, or I need to get ‘specialer,’ ” said Michael Kleinrock, director of research development at the IMS Institute for Healthcare Informatics, a health industry research group. “They all want to be special.”

As one consequence of the approaching cliff, executives for generic drug companies say, they will no longer be able to rely as much on the lucrative six-month exclusivity periods that follow the patent expirations of many drugs. During those periods, companies that are the first to file an application with the Food and Drug Administration, successfully challenge a patent and show they can make the drug win the right to sell their version exclusively or with limited competition.

The exclusivity windows can give a quick jolt to companies. During the first nine months of 2012, sales of generic drugs increased by 19 percent over the same period in 2011, to $39.1 billion from $32.8 billion, according to Michael Faerm, an analyst for Credit Suisse. Sales of branded drugs, by contrast, fell 4 percent during the same period, to $174.2 billion from $181.3 billion.

But those exclusive periods also make generic drug makers vulnerable to the fickle cycle of patent expiration. “The only issue is it’s a bubble, too,” said Mr. Kleinrock. He said next year, the generic industry would enter a drought that was expected to last about two years.  Of the drugs that are becoming generic, fewer have exclusivity periods dedicated to a single drug maker.

In 2013, for example, the antidepressant Cymbalta, sold by Eli Lilly, is scheduled to be available in generic form. But more than five companies are expected to share in sales during the first six months, according to a report by Ms. Vukhac.

Heather Bresch, the chief executive of Mylan, the second-largest generics company in the United States, said Wall Street analysts were obsessed with the issue. “I can’t go anywhere without being asked about the patent cliff, the patent cliff, the patent cliff,” she said. “The patent cliff is one aspect of a complex, multilayered landscape, and I think each company is going to face it differently.”

Jeremy M. Levin, the chief executive of Teva Pharmaceuticals, the largest global maker of generic drugs, agreed. “The concept of exclusivity — where only one generic player could actually make money out of the unique moment — has diminished,” he said. “In the absence of that, many companies have had to really ask the question, ‘How do I really play in the generics world?’ ”

For Teva, Mr. Levin said, he believes the answer will be both its reach  — it sells 1,400 products, and one in six generic prescriptions in the United States is filled with a Teva product  — and what he says is a reputation for making quality products. That focus will be increasingly important, he said, given recent statements by the F.D.A. that it intends to take a closer look at the quality of generic drugs. Mr. Levin also said he planned to cut costs, announcing last week that he intended to trim from $1.5 to $2 billion in expenses over the next five years.

This article has been revised to reflect the following correction:

Correction: December 4, 2012

An earlier version of this article misstated the country in which the pharmaceutical company Endo is based. It is an American company, not Japanese.

Call That Kept Nursing Home Patients in Sandy’s Path

Chang W. Lee/The New York Times

Workers were shocked that nursing and adult homes in areas like Rockaway Park, Queens, weren’t evacuated.

Hurricane Sandy was swirling northward, four days before landfall, and at the Sea Crest Health Care Center, a nursing home overlooking the Coney Island Boardwalk in Brooklyn, workers were gathering medicines and other supplies as they prepared to evacuate.

Then the call came from health officials: Mayor Michael R. Bloomberg, acting on the advice of his aides and those of Gov. Andrew M. Cuomo, recommended that nursing homes and adult homes stay put. The 305 residents would ride out the storm.

The same advisory also took administrators by surprise at the Ocean Promenade nursing home, which faces the Atlantic Ocean in Queens. They canceled plans to move 105 residents to safety.

“No one gets why we weren’t evacuated,” said a worker there, Yisroel Tabi. “We wouldn’t have exposed ourselves to dealing with that situation.”

The recommendation that thousands of elderly, disabled and mentally ill residents remain in more than 40 nursing homes and adult homes in flood-prone areas of New York City had calamitous consequences.

At least 29 facilities in Queens and Brooklyn were severely flooded. Generators failed or were absent. Buildings were plunged into a cold, wet darkness, with no access to power, water, heat and food.

While no immediate deaths were reported, it took at least three days for the Fire Department, the National Guard and ambulance crews from around the country to rescue over 4,000 nursing home and 1,500 adult home residents. Without working elevators, many had to be carried down slippery stairwells.

“I was shocked,” said Greg Levow, who works for an ambulance service and helped rescue residents at Queens. “I couldn’t understand why they were there in the first place.”

Many sat for hours in ambulances and buses before being transported to safety through sand drifts and debris-filled floodwaters. They went to crowded shelters and nursing homes as far away as Albany, where for days, they often lacked medical charts and medications. Families struggled to locate relatives.

The decision not to empty the nursing homes and adult homes in the mandatory evacuation area was one of the most questionable by the authorities during Hurricane Sandy. And an investigation by The New York Times found that the impact was worsened by missteps that officials made in not ensuring that these facilities could protect residents.

They did not require that nursing homes maintain backup generators that could withstand flooding. They did not ensure that health care administrators could adequately communicate with government agencies during and after a storm. And they discounted the more severe of the early predictions about Hurricane Sandy’s surge.

The Times’s investigation was based on interviews with officials, health care administrators, doctors, nurses, ambulance medics, residents, family members and disaster experts. It included a review of internal State Health Department status reports. The findings revealed the striking vulnerability of the city’s nursing and adult homes.

On Sunday, Oct. 28, the day before Hurricane Sandy arrived, Mr. Bloomberg ordered a mandatory evacuation in Zone A, the low-lying neighborhoods of the city. But by that point, Mr. Bloomberg, relying on the advice of the city and state health commissioners, had already determined that people in nursing homes and adult homes should not leave, officials said.

The mayor’s recommendations that health care facilities not evacuate startled residents of Surf Manor adult home in Coney Island, said one of them, Norman Bloomfield. He recalled that another resident exclaimed, “What about us! Why’s he telling us to stay?”

The commissioners made the recommendation to Mr. Bloomberg and Mr. Cuomo because they said they believed that the inherent risks of transporting the residents outweighed the potential dangers from the storm.

In interviews, senior Bloomberg and Cuomo aides did not express regret for keeping the residents in place.

“I would defend all the decisions and the actions” by the health authorities involving the storm, said Linda I. Gibbs, a deputy mayor. “I feel like I’m describing something that was a remarkable, lifesaving event.”

Dr. Nirav R. Shah, the state health commissioner, who regulates nursing homes, said: “I’m not even thinking of second-guessing the decisions.”

Still, officials in New Jersey and in Nassau County adopted a different policy, evacuating nursing homes in coastal areas well before the storm.

Contradictory Forecasts

The city’s experience with Tropical Storm Irene last year weighed heavily on state and city health officials and contributed to their underestimating the impact of Hurricane Sandy, according to records and interviews.

Before Tropical Storm Irene, the officials ordered nursing homes and adult homes to evacuate. The storm caused relatively minor damage, but the evacuation led to millions of dollars in health care, transportation, housing and other costs, and took a toll on residents.

As a result, when Hurricane Sandy loomed, the officials were acutely aware that they could come under criticism if they ordered another evacuation that proved unnecessary.

Study shows growth in second screen users

NEW YORK (AP) — Television viewers were once called couch potatoes. Many are becoming more active while watching now, judging by the findings in a new report that illustrates the explosive growth in people who watch TV while connected to social media on smartphones and tablets.

The Nielsen company said that one in three people using Twitter in June sent messages at some point about the content of television shows, an increase of 27 percent from only five months earlier. And that was before the Olympics, which was probably the first big event to illustrate the extent of second screen usage.

"Twitter has become the second screen experience for television," said Deirdre Bannon, vice president of social media at Nielsen.

Social networking is becoming so pervasive that the study found nearly a third of people aged 18-to-24 reported using the sites while in the bathroom.

An estimated 41 percent of tablet owners and 38 percent of smartphone owners used their device while also watching television at least once a day, Nielsen said.

That percentage hasn't changed much; in fact, 40 percent of smartphone owners reported daily dual screen usage a year earlier, Nielsen said. The difference is that far more people own these devices and they are using them for a longer period of time. The company estimated that Americans spent a total of 157.5 billion minutes on mobile devices in July 2012, nearly doubling the 81.8 billion the same month a year earlier.

"There are big and interesting implications," Bannon said. "I think both television networks and advertisers are onto it."

The social media can provide networks with real-time feedback on what they are doing. The performance of moderators at presidential debates this fall was watched more closely than perhaps ever before, because people were instantly taking on Twitter to provide their own critiques.

It also makes for some conflicting information: Twitter buzzed with complaints last summer about NBC's policy of airing many Olympics events from London on tape delay, yet ratings for the prime-time Olympics telecast soared past expectations.

The increase in people watching television and commenting about it online would seem to run counter to another big trend this fall: more people recording programs and watching them at a later hour. Those contrary trends both increase the value of live event programming like awards shows or sporting events.

The Nielsen study also found that 35 percent of people who used tablets while watching TV looked up information online about the program they were watching. A quarter of tablet owners said they researched coupons or deals for products they saw advertised on television

As rapid as the use of social media while on television is growing in the United States, it already lags behind other countries. Nielsen said that 63 percent of people in the Middle East or Africa report using social media while on TV, and 52 percent of people in Latin America.

The U.S. media survey is based on a representative sample of 1,998 adults in Nielsen's regular TV ratings panel, conducted online between July 19 and Aug. 8. Nielsen's global survey involved more than 28,000 people in 51 countries and was taken between March 23 and April 12, 2011.
