Not even CBS can keep The Big Bang Theory afloat forever.
Star Johnny Galecki now says that CBS’ highest-rated comedy will likely call it quits after twelve seasons, sending off Leonard, Sheldon, Raj, Penny, Howard, Bernadette and Amy as early as 2019. y through its eleventh season, that would place a twelfth and final run ending in May of 2019. It was back in March that CBS renewed The Big Bang Theory for Seasons 11 and 12; each comprised of twenty-four episodes.
Neither CBS nor executive producers may confirm Season 12 as the final Big Bang Theory for some time, but stay tuned for the latest.
The franchise will live on regardless, as CBS also confirmed this past week that prequel spinoff Young Sheldon will return for a second season.
