By the end of the 90's, MTV was looking for the next big hit cartoon. It had been two years since Beavis & Butt-Head had ended, and its spinoff series, Daria, needed something to complement it on the schedule.
Downtown, they say, should've been it. Series creator Chris Prynoski had worked on "Beavis & Butt-Head Do America", and was given the green light to develop his own series. Unfortunately, one season of 13 episodes was all Prynoski got, as MTV, seeing the ratings, cancelled Downtown. Prynoski, however, persevered, and would later work on Megas XLR for Cartoon Network, and Motorcity for DisneyXD. Both of those series were also short-lived for whatever reason.
I never got to see the show, so there isn't going to be a rating. For now, scope the episode, "The Con", with WWE superstar the Undertaker as a special guest star.
