With the Super Mario videogames proving so popular, it was inevitable that Mario would sooner or later receive his own animated TV show, and sure enough in 1989 it happened. In actual fact he had more than one show, but the one I remember most was the Super Mario Bros Super Show.
As I recall it was shown in the UK at the end of TV-am at the weekends (though I might be wrong about that) and it was kind of unusual for a cartoon show because it also featured a couple of live action sections at the beginning and the end.
The cartoon itself was pretty much what you would expect, with Mario and Luigi having to rescue Peach from Bowser in many episodes, all set for the most part in a version of the Mushroom Kingdom not dissimilar to that from the games.
The live action section is what I remember most about the show though, if only because it was cheesier than a 12 pound chunk of cheddar. It featured Mario and Luigi running their plumbing business in Brooklyn, and was basically a bunch of corny sketches which normally bore little in the way of links to the cartoon segment.
