Blue Bloods is sadly coming to an end in late 2024 after 14 seasons, but CBS still plans to expand the franchise with a spinoff, which might be a bit confusing to some, given the network’s decision to cancel the original show. The police procedural series, created by Mitchell Burgess and Robin Green, debuted on September 24, 2010, and as anyone could tell from its 14-season run, the show has been a massive success for CBS. Nevertheless, CBS canceled Blue Bloods in the fall of 2023, with season 14 split into two parts and serving as the series’ final outing.
