It's safe to say the "Big Bang Theory" cast isn't going anywhere--at least for three more years.

Entertainment Weekly reported that the CBS comedy has been renewed for not just one, but three more seasons. The unusual, three-year renewal represents a major vote of confidence in the show, which is the top-rated scripted series on broadcast television.

On average, the show brings in 19.779 million viewers, a 6.1 rating in adults 18-49, and a 7.8 in adults 25-54. "The Big Bang Theory" has ranked the No. 1 sitcom among viewers since the 2010-11 season and continues to hold the top spot for the second straight year.

The renewal also means that the sitcom will reach a total of 10 seasons in the 2016-2017 television year, before any further negotiations are needed. The show is currently on its seventh season.

"Comedy is a big part of our schedule, and The Big Bang Theory is the biggest comedy force on television," said Nina Tassler, CBS Entertainment Chairman, in a statement. "This multi-year deal further strengthens our network's position for future seasons and marks another chapter in the great partnership CBS enjoys with Warner Bros. Television for delivering audiences the best in comedy. We're proud to work with and showcase the incredible talents of Chuck Lorre, Steve Molaro and this amazing cast every week."

Contract renewal negotiations with show stars Jim Parsons (Sheldon), Johnny Galecki (Leonard), and Kaley Cuoco-Sweeting (Penny) are currently in progress. Parsons has won three Emmy Awards for Outstanding Lead Actor in a Comedy Series. The show also stars Simon Helberg, Kunal Nayyar, Mayim Bialik and Melissa Rauch.

"The Big Bang Theory" airs at 8 p.m. ET on Thursdays.
