Parents of small children have long been told to avoid using the television as a babysitter. This week, the nation's leading group of pediatricians reiterated its stance against letting kids under 2 watch any TV at all.

But what about iPhones and iPads?

Even as President Obama announced the troop withdrawal from Iraq Friday, he acknowledged the U.S. now faces a bigger challenge: creating opportunity and jobs in this country.

"After a decade of war, the nation that we need to build — and the nation that we will build — is our own," he said, "an America that sees its economic strength restored just as we've restored our leadership around the globe."

At a recent rally, hundreds of young supporters of Argentine President Cristina Fernandez chanted that her late husband is not dead. In a way, he's not. Celebrated for guiding Argentina out of economic calamity a decade ago, former President Nestor Kirchner is as present in his wife's re-election campaign as she is.

Wearing suits and somewhat harried expressions, veteran actors Michael Rothhaar and Tony Pasqualini blend right in with the lunch crowd of this Los Angeles office building.

As they head into the packed elevator, Rothhaar and Pasqualini jockey for a spot in the back. When the doors close, that's their cue.

"Lord, I think I saw him yesternight," Pasqualini says.

"Saw? Who?" Rothhaar replies.

"Lord, the king your father."

"The king, my father!"

"A figure like your father, armed at all points."

On the evening of Oct. 16, 1859, abolitionist John Brown led 21 men down the road to Harpers Ferry in what is today West Virginia. The plan was to take the town's federal armory and, ultimately, ignite a nationwide uprising against slavery.

On Friday, News Corp. held its first shareholder meeting since a phone-hacking scandal in the U.K. led the company to close a major tabloid. Outside the meeting at Fox Studios in Los Angeles, about 100 demonstrators assembled to condemn the Murdochs and News Corp.'s leadership.

But the complaints that followed inside were far more specific. There was a vote to approve the board of directors, but it was largely a formality because the Murdoch family and its allies control so many voting shares.

Rupert Murdoch wasted little time in reminding investors of his track record.

Florida Sen. Marco Rubio on Friday lambasted the Washington Post for an article claiming that he "embellished" the facts of his parents' emigration to the U.S..

In 2002, when the British rock band Coldplay was on tour with its second album, A Rush of Blood to the Head, frontman Chris Martin said, "I just want to make the best music of all time with my best friends." Since that time, Coldplay, with Jonny Buckland on guitar, Guy Berryman on bass and Will Champion on drums, has become one of the biggest acts in rock.

NPR's Scott Simon spoke with Martin and Champion on the occasion of their fifth album, Mylo Xyloto, due out this week. Martin says that, at the very least, the part about friends is still true.
