Grylls hurt in fall

Bear Grylls, host of Discovery Channel's "Man vs. Wild," was injured while on an expedition in Antarctica unrelated to his duties for the network. Grylls suffered a fall Friday that resulted in a shoulder injury while taking part in an expedition for Ethanol Ventures to promote the potential of alternative energies, the network said. The seriousness of the injury was unknown, but Grylls on Sunday was headed to the U.K. to receive medical attention. The Antarctica expedition was raising money for Global Angels, an international children's charity.

Walters rates well

Barbara Walters gave ABC another ratings lift Thursday night, with her annual "Ten Most Fascinating People" special performing strongly at 10 p.m. Walters' special dominated the hour and outperformed her Thanksgiving-eve Barack and Michelle Obama interview. "Ten Most Fascinating" (13.2 million viewers, 4.2 rating/11 share in adults 18-49) was off just a tad from last year's edition.

Fallon rollout

Jimmy Fallon's online video series ramping up to his "Late Night" takeover is launching today. The videos will go live weeknights at 12:30 a.m. to get fans accustomed to Fallon when he steps in to replace Conan O'Brien next year, after O'Brien takes over "The Tonight Show." The online series allows producers an opportunity to soft-launch the series and figure out what content works best for the new host.
