Mystery Science Theater 3000 (MST3K) was founded in Minneapolis, initially airing on local public access station KTMA before making its national debut on The Comedy Channel/Comedy Central on November 28, 1989. The show, which involves characters riffing on B-movies, later moved to the Sci-Fi Channel, where it continued until August 8, 1999. MST3K's core mission is to provide comedic commentary on lesser-known films, blending humor with a unique viewing experience. The show has since expanded into digital platforms, including the Gizmoplex, an online space for streaming new content and engaging with fans.

Notable figures associated with MST3K include original cast members Michael J. Nelson, Bill Corbett, and Kevin Murphy, who have continued to contribute to the show's legacy through various projects. The series has garnered a dedicated fan base and critical acclaim, leading to successful Kickstarter campaigns that funded new seasons. MST3K's impact is evident in its influence on modern comedic commentary and its enduring popularity, which has spurred revivals and continued engagement through live events and digital content.
