Since its debut nearly 25 years ago, SpongeBob has become a cornerstone of Nick’s lineup, as well as a juggernaut of children’s entertainment at large. In addition to its 13 seasons and counting, the show has spawned three theatrically-released feature films and two spin-off series. A fourth big-screen SpongeBob movie is in the works, as are three streaming-exclusive spin-off films.
It was in 2012 — during Season 8 — that SpongeBob became Nickelodeon’s longest-running animated series in history. With the airing of its 173rd episode, the show broke the record previously held by Rugrats — and has only padded its lead in the decade-plus since.
