Background

CBS had renewed the show for an eleventh and twelfth season in March 2017. On August 22, 2018 CBS and Warner Bros. Television confirmed that this would be the last, a decision that followed Jim Parsons' choice to leave if the show were renewed for a thirteenth. The premiere aired on a Monday, after which the series went back to its regular Thursday slot on September 27 once CBS's Thursday Night Football games moved to Fox.

A retrospective special, Unraveling the Mystery: A Big Bang Farewell, hosted by Galecki and Cuoco, aired the night of the finale after the Young Sheldon season two finale, and is included on the season's DVD and Blu-ray.
