Back in the mid-1990s Cartoon Network did a series called "What a Cartoon", which was a shorts program where various creators did a short that would then be considered for a series.
Much of it were produced at Hanna-Barbera in LA area, but some were made in other parts of US (or sometimes outside; one was done in Italy). One short, "O Ratz: Rat in a Hot Tin Can", was done in Indianapolis at Perennial Pictures. It was animated there, too. One of the very few TV cartoons that wasn't outsourced to Asia.
