how long did gunsmoke tv series run
NBC has officially canceled Law & Order, meaning the show wonât beat Gunsmoke as televisionâs longest-running prime time drama series. Instead, the two dramas will stay tied at 20 years. Gunsmoke ran from 1955 to 1975; when Law & Order wraps up later this month it will have been on the air from 1990-2010). Gunsmoke, however, produced 635 episodes (233 thirty-minute episodes and 402 hour-long episodes) compared to 456 for Law & Order. Furthermore, while James Arness stayed with Gunsmoke through its entire run, there are no original cast members still on Law & Order.
