The FOX network's most successful series to date was a spin-off from The Tracey Ullman Show. Originally appearing on that series as a 1 minute filler, the executive producers of that series, James L. Brooks & Sam Simon decided that these characters could support a half hour series. So they did it and started the longest running animated series in primetime network television.
