Big Brother: After Dark (often shortened to BBAD) is a spinoff of the American reality series Big Brother. The program debuted on Showtime 2 in the United States and Slice in Canada on July 5, 2007, as a companion show launched in conjunction with the eighth season of Big Brother; it moved to TVGN (now Pop) on June 26, 2013, coinciding with the debut of the fifteenth season of the parent series. A Canadian version of Big Brother: After Dark was also developed as a companion series to Big Brother Canada, also airing on Slice. The series did not return with the 22nd season of Big Brother in 2020 nor the two seasons after that. It is unknown why but some say it could be due to the Viacom and CBS merger that took place in 2019.
