"Rugrats" was Nickelodeon's second Nicktoon, debuting on the same day as "Doug" (which premiered before it) and "The Ren & Stimpy Show" (which debuted after). The first run of the series was produced from 1990 to 1993 before production went on a hiatus (episodes that had not yet been released at that point continued to be released through 1994). Between 1995 and 1996, only two Jewish-themed specials premiered, and the rest of the series aired in reruns. Production on new episodes restarted in 1996 and the show aired in Nickelodeon's SNICK block from 1997 to 2001. From 1994 until 2012, "Rugrats" was the longest-running Nickelodeon animated series, with 172 episodes produced across its 13-year run. It was surpassed in 2012 by "SpongeBob SquarePants" with the episode "Squiditis/Demolition Doofus" that year.
