The 12th season of CBS’ The Big Bang Theory will be its last. 

CBS, Warner Bros. TV and Chuck Lorre Productions announced the news in a joint statement.

“We are forever grateful to our fans for their support of The Big Bang Theory during the past twelve seasons. We, along with the cast, writers, and crew, are extremely appreciative of the show’s success and aim to deliver a final season, and the series finale, that will bring The Big Bang Theory to an epic creative close.”

EW reports that the series is ending because star Jim Parsons was ready to walk away from the series. And since there is no show without Dr. Sheldon Cooper, the 12th season will mark the end of the longest-running multi-camera series in TV history.

Three weeks after CBS Entertainment head Kelly Kahl said that this isn’t the series’ final year and that they are in “preliminary discussions to renew the show with Warner Bros” he released the following statement:

The Big Bang Theory has been the defining comedy of its generation. All of us at the Network take exceptional pride in this series that uniquely combines creative genius, commercial ratings success, cultural influence and characters who became so popular, they are easily known by just one name. We’re incredibly grateful for our partnership with Warner Bros., Chuck Lorre Productions and a brilliant cast and crew that has made such a ‘big bang’ and lasting legacy on the television landscape.”

Season 12 of The Big Bang Theory will premier Monday, September 24.
