After just a year away, Spider-Man returned to Fox's Saturday morning lineup in 1999, only to discover just how much the ratings landscape had changed in his absence.
In Spider-Man Unlimited, the web-head heads for Counter Earth to retrieve astronaut John Jameson, son of Daily Bugle editor-publisher J. Jonah Jameson. Here's the intro:
Pokemon, having been a mid-season pickup by WB earlier in the year, is the hottest cartoon on the planet at the time, and blows away Spidey in the ratings, such that Fox pulled the plug after less than a month. Didn't help that the series was late in starting for reasons known only to the network. Unlimited would later return to burn off the remaining episodes. Marvel produced a companion comic book, which also was given a quick hook.
As with Avengers: United They Stand, which bowed that same season and ran into the same problems, Unlimited was produced by Saban in conjunction with Marvel's own animation studio, and was one of the last entries in this collaboration (Silver Surfer was also part of this group). Spidey, of course, has since recovered to star in two more series since. DisneyXD holds the cable rights to the series, but doesn't run it in key air slots.
