Cancellation
The show's creators were striving to reach 65 episodes. 26 episodes of The Spectacular Spider-Man were produced in total.
The series stopped production with a renewal dependent upon the ratings for season 2 on the U.S. Disney XD channel and the sales of the DVDs. If the third season were to have gone ahead, producer Greg Weisman stated that Scorpion and Hobgoblin would have made their appearances. On September 1, 2009, the television rights for Spider-Man were returned to Marvel by Sony. The effect this had on The Spectacular Spider-Man's future was unknown. At the time, President of Marvel Animation Eric Rollman further stated that "no decisions have been made either way" regarding the fate of the series. Newsarama reported that the series' cancellation occurred just after The Walt Disney Company acquired Marvel Entertainment in December 2009.
On April 13, 2010, Marvel announced that a new series entitled Ultimate Spider-Man based on the Ultimate Spider-Man comic book storyline was aired on Disney XD April 1, 2012. The same day, Greg Weisman told IGN: "I've heard nothing directly from Marvel, but I think the Ultimate Spider-Man announcement makes it fairly clear that Spectacular is over." Marvel Animation and Sony also commented on this to Marvel Animation Age, confirming that the series has ceased production. A post fleshes out an interesting confluence of events that possibly resulted in Season three not being produced.
