It seemed like it would go on forever, but The Big Bang Theory actually does have an expiry date – the end of its 12th season.

The crazy-successful Chuck Lorre show that skewers all things nerdy will be going out on a high, as it still dominates the ratings.

It will also be in the record books, as the longest-running multi-camera series in TV history, clocking up 279 episodes by the time it ends.

The news has come as a bit of a surprise, as mere weeks ago the show’s network CBS were talking of there being more seasons to come. But now, this…

“We are forever grateful to our fans for their support of The Big Bang Theory during the past twelve seasons,” reads a joint statement from CBS and Chuck Lorre Productions. “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.”

Cynics could suggest that they just don’t want to have to negotitate new contracts with the cast, the original five of whom are already the highest-paid actors on TV, nabbing them around US$1 million an episode. Wow.

So, The Big Bang Theory will go out on a high. Bang! The final season starts airing in the US in late September.

While you wait, have some season 11 bloopers (possible spoilers, etc.)
