A Texan and a 90s Kid? This Was Probably Your Favorite Cartoon!
As someone who deeply loved (and still loves) cartoons, the 90s shaped my tastes, style and sense of humor.
Using Google Trends data and excluding anything that technically started in the 80s or deemed "adult" (think South Park), the most popular 90s cartoon in Texas is Recess, a cartoon I barely remember.
I can't even pick a definitive personal favorite, but I've narrowed it down to three: Batman: The Animated Series, which is a favorite of many states and the most popular of all. It was also the genesis of Harley Quinn as we know her today.
Sailor Moon is California's favorite and arguably the most recognizable anime of all time. And the delightfully expressive and gleefully gross Ren & Stimpy, which is Washington's favorite and the first cartoon to use paintings for very detailed scenes. (Spongebob Squarepants later took that trick over with style.)
