'Big Bang Theory' Renewed For Three Years

CBS says it’s renewing its hit comedy “The Big Bang Theory” for three more years.

The extraordinary three-year deal would carry TV’s most-watched sitcom through the 2016-2017 season, the series’ 10th on the air.

“The Big Bang Theory” premiered in September 2007 and has been a ratings smash for virtually its entire run. It has averaged nearly 20 million viewers each week this season.
