Surprising to think Rugrats lasted as long as it did, it was created alongside Doug and Ren & Stimpy but outlived both of those shows by some considerable degree, and got its own spin-off in the process.
Nickelodeon’s Doug was originally commissioned as a 65-episode run, but in the end Nickelodeon only paid for 52 episodes. ABC had shown interest in taking up the show and in 1996 when Disney purchased ABC they also purchased Doug, renaming it
Brand Spanking New! Doug
, but by the time Disney acquired the show, creative changes had been made, notably Billy West, who voiced Doug in the Nickelodeon series, had moved on to other projects.
