Target said its new program relies on shoppers using their Facebook accounts. However, shoppers can only redeem the offers they choose in Target's U.S. stores, not online.

With Cartwheel, shoppers select the deals they want online and then bring a barcode - either on paper or on a mobile phone - to a Target store to get the discounts. Shoppers can see what offers their Facebook friends have chosen, and earn more offers by having their Facebook friends sign up.

This service comes as traditional retailers try to keep shoppers buying from them rather than from Amazon.com Inc and other online-only retailers, especially as shoppers use their smartphones to compare prices.

Twenty percent of cellphone owners research products using their phones before they buy, and 18 percent of them compare prices on their phones before making a purchase, according to Bill Tancer, general manager of global research for Experian Marketing Services.

Cartwheel follows efforts such as Wal-Mart Stores Inc letting shoppers in some of its U.S. stores scan their goods with their iPhones while they shop and then more quickly proceed through a self-checkout lane. Sears Holdings Corp's "Member Assist" program gives its loyal shoppers the ability to get personalized shopping advice from in-store personnel without even stepping foot in a Sears or Kmart store.

"It is very fascinating to see the very different approaches that retailers are taking to achieve the same goals," said Carol Spieckerman, president of newmarketbuilders, a retail strategy firm.

Retailers are using digital tools to better cater to shoppers who love to comparison shop while in their stores. Target and other retailers offer free WiFi, and at one of its Minnesota stores Best Buy Co Inc has tested its "Page a Blue Shirt" service that lets customers summon a store associate with a click on a store iPad.

For chains such as Kmart, Target and Walmart, such issues are increasingly important as their businesses have evolved since each opened its doors in 1962. Their stores used to be one-stop shops for everything from books and movies to photo developing. As such services have waned in popularity with the rise of digital books, movies and photo sharing sites, the chains are doing what they can to figure out new ways to make their stores more attractive to shoppers and, ultimately, more profitable.

CARTWHEEL'S BETA ROLLOUT

Starting on May 8, Target is opening Cartwheel to the public in a beta test, and asking for feedback as it makes changes. The service will initially be advertised on Target's website, through Facebook and in emails to Target's best shoppers and card holders.

Target did not rule out the possibility of allowing Cartwheel offers to be redeemed on its website someday.

Target said it worked in a close partnership with Facebook Inc for about a year. While Facebook has worked on the project, Cartwheel is owned by Target. For now, Target has no plans to extend it to other social sites such as Pinterest.

Linking offers through Facebook will let the retailer know exactly what Facebook can or cannot accomplish for it. While Twitter can be useful to promote timely, limited offers, Facebook is "the dominant platform" for connecting with shoppers and, in turn, with their connections, Spieckerman said.

Target sees the program as a way to extend the trips shoppers take into parts of the store they might normally skip, in order to pick up a promoted item. An app coming in June will let shoppers scan a photo of an item's barcode to quickly see if an offer is available on that item.

Shoppers using Cartwheel can choose from hundreds of deals on items such as Target's own Threshold home goods and name brand goods such as M&Ms candy and Coca-Cola soft drinks. The weekly, monthly and quarterly deals include discounts from 5 percent off to as much as 40 percent off of certain goods, and differ from other Target offers in circulars or coupon booklets.

Shoppers can share the deals they are picking with their Facebook friends, but offers on more discreet items - from bras to Tums - will not be visible to others.

The device injects the patients who have different types of colonoscopy procedures with propofol, a minimal-to-moderate sedation agent widely used in colonoscopy procedures.

The system reduces the risks of oversedation when compared to other traditional methods, Johnson & Johnson said in a release, with 99 percent of patients recovering from the effects within 10 minutes after administration of the drug.

J&J said the system is expected to be introduced on a limited basis beginning in 2014.

The company estimates that 15 million patients in the United States are candidates for these procedures.

His suspension will begin immediately, meaning he'll miss the last four games of this season and the first six of next season, the English Football Association said Friday.

The Uruguay international bit the upper arm of Chelsea's Branislav Ivanovic during a 2-2 draw on Sunday. Suarez apologized to Ivanovic after the match, was fined by Liverpool and earned the wrath of the British Prime Minister.

On Friday, Suarez posted a statement on his website that said he chose not to appeal to avoid giving "the wrong impression."

"I would like to explain to everybody that I decided to accept the ban because whilst 10 games is clearly greater than those bans given in past cases where players have actually been seriously injured," Suarez said on the website, "I acknowledge that my actions were not acceptable on the football pitch so I do not want to give the wrong impression to people by making an appeal."

The English Football Association decided the regular three-match ban for violent conduct was insufficient in this case, and an independent panel decided Wednesday to add seven more games.

Prime Minister David Cameron said Friday that Suarez, the league's second highest scorer with 23 goals, has set an "appalling" example to youngsters by biting a fellow player and welcomed the tougher sanction.

"I made my own views clear just as a dad watching the game," Cameron told the BBC. "I've got a 7-year-old son who just loves watching football and when players behave like this it just sets the most appalling example to young people in our country."

Suarez could have lodged an appeal against the extra seven games. If unsuccessful, he risked the possibility of the FA extending his sanction for making a frivolous appeal.

"I hope that all the people who I have offended at Anfield last Sunday will grant me forgiveness and I again repeat my personal apology to Branislav," Suarez said.

It's not Suarez's first offense for biting an opponent. In November 2010, he was banned for seven matches for biting a PSV Eindhoven player in the Dutch league, earning the nickname "Cannibal of Ajax."

Despite widespread condemnation of his actions, broadcast live to a global television audience, the striker has been passionately defended by Liverpool manager Brendan Rodgers and teammates.

They believe Suarez was treated harshly by the FA because of his past disciplinary record. Along with biting a player in 2010, Suarez was suspended eight games for racially abusing Manchester United defender Patrice Evra in 2011.

"We are all disappointed at the severity of the punishment and in particular the differing standards that have been applied across various previous incidents," Liverpool managing director Ian Ayre said in a club statement.

"Luis is an important member of our team and nothing has changed in that regard. We are committed to helping him improve his conduct and he will be given our full support."

Rodgers added in the statement that the club had to "move on and support Luis in his decision."

Cameron believes the punishment fits the behavior on the field.

"I've read in some newspapers, who think somehow this isn't serious," Cameron said. "I think it is serious, when we're trying to bring up our children properly, they do see football players as role models."

Actually, we were the 15th seed," Miller said.

And ultimately, the last one standing.

Miller capped his brilliant career with a breakaway goal in the third period, Jeff Malcolm stopped all 36 Quinnipiac shots and the Bulldogs won their first NCAA championship with a 4-0 victory Saturday night.

It was sweet revenge for Yale (22-12-3), which lost the three previous meetings with the top-seeded Bobcats by a combined 13-3. The nation's oldest hockey program, however, left no doubt in the final, riding the play of Malcolm and some unlikely offensive contributions to capture a title 117 years in the making.

"Tonight was our turn," Yale coach Keith Allain said.

The Bulldogs have been playing hockey since 1896 but had only made the tournament twice before Allain took over in 2006. The Yale graduate accepted the job with the promise from his bosses the school would do what it takes to be competitive. In seven seasons he guided the Bulldogs all the way to the top.

"I came back to prove you could go to the best university in the world and prove you can play hockey at the highest level," Allain said.

Yale did it throughout the tournament, knocking off three No. 1 seeds, including its Connecticut rivals from just down the street. Quinnipiac (30-8-5) located less than 10 miles from the Yale campus spent most of the year ranked No. 1.

The Bobcats (30-8-5) hardly looked like it after Yale's Clint Bourbonais redirected a shot between goalie Eric Hartzell's legs with 4 seconds left in the second period and freshman Charles Orzetti scored his first goal in four months 3:35 into the third to make it 2-0.

Miller, the tournament's Most Outstanding Player, then broke loose and flipped a backhand by Hartzell for his 18th goal of the season. Pittsburgh native Jesse Root added an empty netter to set the coronation in motion.

"You've got to play your game," Miller said. "We had some great players on our team. A lot of guys that don't get noticed, they're our heroes."

Hartzell stopped 27 shots, but the Hobey Baker finalist let in a couple of soft goals that gave Yale all the momentum it would need.

"I thought we were the best team in college hockey for the season," Quinnipiac coach Rand Pecknold said. "Unfortunately, we didn't prove it tonight."

The Bobcats dominated the season series, sweeping all three meetings by a combined score of 13-3. Quinnipiac trailed for all of 18 minutes in the three games combined and Hartzell allowed only one goal in the previous eight periods against Yale.

Yet Pecknold insisted the Bulldogs weren't the same team the Bobcats steamrolled 3-0 three weeks ago in the ECAC tournament consolation game. Yale tripped up national powers Minnesota and North Dakota to make the Frozen Four for the first time since 1952, then edged UMass Lowell 3-2 in overtime in the semifinals Thursday.

On the biggest stage, the Bulldogs finally put it together behind Malcolm.

The senior celebrated his 24th birthday by keeping the tournament's highest-scoring team at bay, including a crucial 5-on-3 penalty kill in the second period that kept the game tied. The Yale fans serenaded the goaltender with "Happy Birthday" during one stoppage in play, and Malcolm responded by taking turning away Yale's nemesis one breathtaking stop at a time.

Ultimately, Hartzell blinked first.

The clock winding down late in the second period, Young flipped what appeared to be an innocent shot from just outside the left circle. Bourbonais slapped his stick on the ice just as the puck rolled past him a few feet in front of the crease. The change of direction sent the puck between Hartzell's legs to give Yale an unlikely lead and a major boost heading into the final intermission of the season.

Quinnipiac attempted to respond early in the third, flying around the Yale net in the same way the Bobcats overwhelmed St. Cloud State on Thursday. Malcolm, in perfect position nearly every time, maintained his composure.

His teammates repaid his hard work with another unlikely goal. Orzetti, a freshman who hadn't scored since Dec. 8, streaked down the left wing and fired a shot at Hartzell. The rebound trickled to Hartzell's right and Orzetti slammed home his own rebound between the goalie's legs to give the Bulldogs a 2-0 lead.

The soft goals were uncharacteristic of Hartzell's outstanding season. Yet they counted anyway.

"Without Hartzy we're not here, we don't go to the Frozen Four," Pecknold said."He was awesome all year for us."

Just not in the final 21 minutes of the season.

Miller, who scored in overtime in the semifinals against Lowell, broke through 9:06 into the third to make it 3-0. The Bobcats panicked, pulling Hartzell with 7:19 remaining.

The ploy lasted all of 20 seconds. Root delivered the puck into the empty net and drained any drama out of the final 7 minutes. Confetti rained down at the final horn as the Bulldogs mobbed Malcolm in celebration.

"In the NCAA tournament anybody can beat anybody," Miller said. "Whoever has the hottest goalie, best team game wins."

LOS ANGELES (TheWrap.com) - Brad Pitt told theater owners on Monday night that he was inspired to make "World War Z" because he wanted to star in a film that his kids not only could see, but would want to see before they turn 18.

Based on the footage that the actor and Paramount Pictures brought to CinemaCon on Monday, his children better have strong stomachs. The roughly 20 minutes that was screened in Las Vegas at the annual trade show for exhibitors was terrifying and intense.

It also demonstrates that Paramount spared little expense in staging the zombie pandemic at the center of the film. That could be risky. After all, "World War Z" arrives in theaters this summer boasting a best-selling novel by Max Brooks, but lacking the name recognition of "Star Trek Into Darkness," "The Hangover Part III" or any of the 17 sequels that will unspool in theaters as temperatures climb.

As if to answer any naysayers, Rob Moore, vice chairman of Paramount Pictures, struck a note of confidence during his studio's presentation, by declaring that "World War Z" was the most anticipated original film of the summer.

That could be corporate hyperbole, but it is safe to say that it is likely the most global in scope. The sequence, Pitt unveiled for theater owners hopped from a traffic-clogged thoroughfare in an American city to Jerusalem to a frightening mid-air confrontation with zombie hordes that should have the same chilling impact on airtravel-phobes as last year's "Flight."

In the sequence set in the Middle East, the walls of the holy city are breached by zombie masses while Palestinians and Israelis flee in terror, while the American showpiece follows Pitt and his family as they dodge explosions, car crashes and a metastasizing collection of zombies.

Here's hoping Pitt's progeny have a healthy tolerance for the undead, because in the in-flight action scenes, the star is forced to toss a hand grenade down an airplane aisle after a zombie stowaway quickly turns passengers into flesh-eating menaces. It's not for the faint of heart.

"World War Z" hits theaters on June 21, 2013. Also known as the date when the Pitt-Jolie household starts having nightmares.

LOS ANGELES (TheWrap.com) - Led Zeppelin, that band that wrote the book on heavy rock, is now helping to rewrite the book on digital publications.

Acclaimed rock photographer Neal Preston's new e-book breaks ground for the genre with interactive video, 80 contact sheets and photos never previously published.

Preston followed the band throughout the '70s and opened up his vast archive to create a rich, intimate experience with the world of Jimmy Page and Robert Plant.

Sharon Waxman grilled Preston on "Led Zeppelin: Sound and Fury," which was published on Monday and available on iTunes. You've had this archive forever, but you only published many of these photos now. Were you just waiting for the iPad to be born?

No. I wasn't even waiting for computers to be born. This is the direction that book publishing is taking. It's a little leap of faith, we're in uncharted territory here.

How so?

It differs exponentially from a traditional coffee-table book. The photos look killer on the new iPad with the retina display. It was a way to really give the fans even more of what they so crave - all that behind-the-scenes stuff. In this kind of book you can include so much more -- audio captions, video interviews.

You shot that famous photo of Jimmy Page drinking from a Jack Daniels bottle backstage. Do you tell that story?

There's audio caption of taking that photo. Sometimes you remember shooting a picture, sometimes you don't. I remember that photo. I happened to be sitting to his right in the dressing room; I had a Nikon with a 24mm lens on my lap, and I was going to say something to Jimmy and I saw the bottle move toward his mouth and I picked up the camera, shot one frame, and I don't know if he even realized I was there shooting it.

Was he upset that you published it?

I don't believe we released that photo initially. I was brought in to work for them. In 1970 I was 18 and I ended up at press conference to announce that Led Zeppelin had supplanted the Beatles as No. 1 band in the world in a MelodyMaker poll.

The reason I was hired was they were notoriously cloistered. Not secretive but with very small inner circle unlike the Stones, when Mick Jagger had 100 people getting his laundry. It was pretty amazing they let any photographer come in and have the run of the store. I was that guy.

How did that come about?

Danny Goldberg, their publicist, hired me. I'd done work for the band through Atlantic Records. He called me up and said: "Pack your bags if you want to go on tour with us." I got that call in November 1974. January 1975 I was working for them.

What's so great about these images is you really feel like you're on stage with those guys.

In one of those, Jimmy's looking right at me, there's dry ice, you see Robert - during song called "No Quarter." Right after I shot that he came up to me and started talking to me. Reason I love that photo is that it feels like being on stage with Led Zeppelin. It sucks you right in.

Access is the currency I have to trade in. Night after night, day after day, week after week, as a photojournalist, you become invisible. When you become invisible, that's when you can capture the magic.

Did the band approve the photos in book?

No, the band was not part of this book, though they received it and I understand they like it very much. This was a different platform, and a new one, and one that hasn't really been exploited in terms of this kind of book, this kind of band.

This book is $9.99 - it's inexpensive compared to a coffee-table book. Is this the world photographers live in now? It's a digital book. You can't have tactile experience with it. However, this is the way publishing is going. There are two things that I hope people get out of this book. One is for the fans, it's a total wet dream. It's right up the vein.

To get the contact proof sheet - you start to see photographically how I think. They can hear the stories they wouldn't hear unless they were up in my house having dinner. And I hope fans get a sense of how much of myself I've put into this book.

I'm very proud of my writing. Stevie Nicks did my intro, because back in the day, she was the first person who sat and looked at a stack of my prints, and said, "You've got to do a book."
