In addition to the main”two shorts” format of Ren and Stimpy, the show often had short sketches as well, like Ask dr. Stupid,Log, various commercials, and the “what’ll we do ‘til then???” sign-offs (which I feel they should have done more). I wonder why that was the only Nicktoon series to do this (Kablaam doesn’t count).
The first three Nicktoons were all very different from each other, with Ren and Stimpy being the most bizarre and gross-out. Doug was tame compared to the others and perhaps the most realistic, while Rugrats might have been a little close to Doug but also having a lot of gross-out humor.
At first, Ren and Stimpy was the hit of the three, getting most of the network and licensing attention during the early 1990s. The first two additions to the Nicktoons - Rocko’s Modern Life and Aaahhhh Real Monsters - were more like Ren and Stimpy, in terms of having animal/fantasy characters and bizarre gross-out humor. I think Hey Arnold is the first addition to include humans and be a bit more normal, almost a mix of Doug and Rugrats.
Often, when a show becomes a big hit, networks want more shows like it. In the late-1990s, Rugrats suddenly became very popular, the kind of show Nickelodeon focused its attention on. And yet I can not really think of any shows that were knock-offs (I know, I said Hey Arnold might have some of its humor). Can anybody think of any shows that seem like knock-offs of Rugrats?
Then again, Klasky Csupo was the first animation production company to get a second Nicktoon, which I think was before Rugrats boosted in popularity, and it is the only animation studio I can think of to have multiple shows on Nickelodeon (despite Ren and Stimpy’s popularity, Nick didn’t order more shows from Spumco or Games Animation, though considering their poor working relationship with John K., I guess they wouldn’t want another show from him).
