The Fox animated staple “The Simpsons” hit a milestone Sunday night that only one other scripted prime-time show in the history of television has reached.
The Fox comedy aired its 600th episode, joining a club that also includes only “Gunsmoke.” The CBS Western ran for 20 seasons and chalked up 635 episodes.
“The Simpsons” reached the milestone in 28 seasons.
Deadline.com notes that the show that’s closest to “The Simpsons” on the list is “Lassie,” which aired 591 episodes over 19 seasons on CBS and in syndication to hold down the No. 3 spot on the all-time list.
