The Big Bang Theory (season 12)


The twelfth and final season of the American television sitcom The Big Bang Theory premiered on CBS on September 24, 2018. The series returned to its regular Thursday time slot on September 27, 2018. The series concluded on May 16, 2019.

Production

In March 2017, CBS renewed the series for two additional seasons, bringing its total to twelve, and running through the 2018–19 television season. On August 22, 2018, CBS and Warner Bros. Television officially announced that the twelfth season would be the series' last. This stemmed from Jim Parsons' decision to leave the series at the end of season twelve if the show were to have been renewed for a thirteenth season. The series concluded with an hour-long finale consisting of two back-to-back episodes on May 16, 2019. A retrospective, hosted by Johnny Galecki and Kaley Cuoco, aired at 9:30 P.M. ET/PT, the night of the finale, following the season two finale of Young Sheldon.
