Say it ain’t so! CBS has officially announced that The Big Bang Theory is ending after the show’s upcoming Season 12. The network confirmed the sad news in a statement after months of rumors on Wednesday, Aug. 22. 

“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 series finale, that will bring The Big Bang Theory to an epic creative close,” the message read.

When Big Bang — which famously stars Johnny Galecki, Kaley Cuoco, Jim Parsons, Kunal Nayyar, Simon Helberg, Mayim Bialik, and Melissa Rauch — ends after 2019’s Season 12, it will be the longest-running multi-camera comedy in TV history. The hit show first premiered back in September 2007 and has since garnered 52 Emmy nominations and won 10. When it wraps next year, the entire series will include 279 episodes. 

In January of this year, actor Johnny sent fans into a tailspin when he hinted that Season 12 of Big Bang could be the show’s final run. “The only manner in which the cast has discussed wrapping [The Big Bang Theory] has been that we’re all going to be very sad when that day comes,” he said at the time. “But I think at this point, everyone’s very comfortable with 12 seasons being a good time to go home and see our families.” 

The show has become so popular that a spin-off series titled Young Sheldon premiered on CBS in September 2017. The program’s second season is set to begin on Sept. 24 of this year. The final season of The Big Bang Theory will premiere on Monday, Sept. 24 at 8 p.m. on CBS before moving to its regular time period on Thursday, Sept. 27 at 8 p.m.
