NBC's joined ABC this season in offering streaming versions of their prime-time shows on online for free. You can watch ad-supported shows on NBC.com after October 1 using their proprietary video player. In addition, NBC is forcing their shows to do a live blog after their premiere episode this season, so you can catch that online as well.
The first four episodes of the shows 30 Rock and Twenty Good Years, plus the first eight episodes of Kidnapped, Friday Night Lights, Studio 60 on the Sunset Strip and Heroes will be online for streaming. Will this online content save NBC from being the last place network again this season? We'll see.
