Longest-Running Sitcom Record Holder
The longest-running American sitcom by number of seasons is the NBC comedy "Cheers", which aired 11 seasons from 1982 to 1993 and produced 275 episodes, setting a benchmark for longevity in the sitcom format. By total episode count, the animated series "The Simpsons" holds the record, with more than 750 episodes across more than 35 seasons as of the latest updates, making it the longest-running scripted primetime series in television history.
Other long-running sitcoms include "It's Always Sunny in Philadelphia," which surpassed 15 seasons on FXX and FX, and "Modern Family," which ran 11 seasons on ABC, illustrating how multi-camera and single-camera formats can both sustain long runs when paired with stable ratings and syndication demand.
Networks, Production Companies, and Business Impact
Networks such as NBC, ABC, Fox, and Warner Bros. Discovery have relied on long-running sitcoms to anchor their schedules and drive affiliate fees, with syndication and streaming licensing creating a durable revenue stream that often outlasts the original broadcast window.
Production companies behind these series, including Warner Bros. Television, 20th Television, and Universal Television, benefit from backend profits, international distribution, and digital licensing, while the shows themselves become valuable IP assets that can be monetized across platforms for decades.
