The Big Bang Theory is coming to an end with the forthcoming season twelve serving as the swansong for the rating giant.

When CBS picked up The Big Bang Theory for two further seasons back in 2016, it was widely expected that these would be the final hurrah for the geek-centric sitcom.  CBS Entertainment president Kelly Kahl previously hinted that they were open to making more episodes, but the decision to end the show is reportedly a creative one from the producers to go out on top. 

In a shared statement, WBTV, CBS, and Chuck Lorre Productions promised "an epic creative close" to the series.

“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.”

Kelly Kahl added in a separate statement;

“The Big Bang Theory has been the defining comedy of its generation,” Kahl said today. “All of us at the Network take exceptional pride in this series that uniquely combines creative genius, commercial rating 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.”

Since its launch in 2007, The Big Bang Theory has consistently drawn massive numbers and is a big money spinner thanks to is syndication deals including Netflix. The show might have peaked six seasons or so ago, but the exploits of Sheldon and the gang hasn't lost any of its appeal with the fans. The final season kicks off in the US on September 24, UK fans will have to wait a little longer as there's no fixed date for when it will return to E4.

On the slightly more optimistic side, spin-off series Young Sheldon (which is surprisingly good) is also back later this year for new episodes.
