The Big Bang Theory has been renewed for an additional three seasons, keeping the show on air through its seventh season in 2013/14.

Nina Tassler, President of CBS Entertainment, said "It doesn't take a theoretical physicist to see why this show is a BIG part of our comedy future, From ratings to critical acclaim to pop culture buzz, it's struck a chord on all levels. The creative genius of Chuck Lorre and Bill Prady and the on-camera talents of an amazing young ensemble have created a comedy that will entertain viewers for a long time. We're proud to partner with Warner Bros. on another highly successful, long-running comedy."

"We are delighted and grateful that CBS has once again rewarded THE BIG BANG THEORY with a multiyear renewal," said Peter Roth, President of Warner Bros. Television. "This is a testament to the inspired and brilliant work of the show's entire creative team, and we look forward to continuing this highly successful partnership."
