So of this:
We have 10 characters who debuted in the 90s (and of those, 3 aired more than half their seasons in the 90s, the rest ran at least half, if not almost entirely, into the 00s +). Of all the characters,
15 were on the air (new episodes) during the 2000s.
Spongebob is absolutely not a 90s show- era of generation is far from the most defining factor of a series. It debuted in May of 1999- so exactly 8 months of the decade had Spongebob. Meanwhile, it is now in its 4th decade of existence, airing for the entire duration of two of those decades, and only in this 4th decade has now added two more shows to its repertoire.
Rugrats may have debuted and aired primarily in the 90s, but it has just gotten a modern day reboot- which is a pretty potent statement.
Avatar Studios opened up last year, making any of those characters a pretty big deal, since (i believe) no other Nicktoon has ever had an entire studio devoted to it.
So, if you want to play those numbers as if that is 90s bias- that's really on you, and not reflective of the context of the shows.
- Majority of the shows were on during the 2000s, many with far more episodes in the 2000s
- Several of the 90s shows have received reboots since the 90s, with multiple currently airing
- Many of the shows from the 90s weren't even highly popular until another decade
- It disregards that 1991 and 1999 are as far apart from each other as 1999 and 2008, and time is not a stepwise function, it is a linear graph
I don't personally disregard all the other information just to say that the 90s is being favored. The next step would be to see how many shows debuted in each decade, and how many of those shows ran for more than 2 seasons. I would heavily bet that the 90s had significantly more debuted shows that ran for over 2 seasons, therefore has a significantly larger pool of characters that would seem viable for play.
Even with that, there is an extreme bias shown for shows that aired new episodes during the 2000s, compared to shows that debuted in the 90s. Therefore, the '00s era of shows,' which consists of shows airing during that decade, regardless of year of conception, is the most represented decade, despite Nickelodeon rising to fame in the 90s. Of the characters in the roster, 13 of the 18/19 (I count Ren and Stimpy as one, but we don't yet actually know) ran for five or more years. I'm not sure how many more shows there are that ran this long (Nicktoon wise) that have a run that long, other than JNBG and FoP.
Another point of note- the three biggest (money wise) franchises (cartoon) that Nintendo owns are Spongebob, TMNT, and Avatar. After this, I believe it is actually the Winx club.
Personal speculation: The shows which got the most publicity for Nickelodeon association are:
- Rugrats
- Spongebob
- Avatar
- TMNT
- Jimmy Neutron
- Fairly Odd Parents
