I'm thinking JK Simmons was probably busy with other animated projects for J. Jonah Jameson to appear in all four seasons. I mean, less than 2 weeks after Ultimate Spiderman came out, Legend Of Korra came out, where he voiced Tenzin. He also had other voice roles that came out very late in the series, such as in Kung Fu Panda 3 and Gravity Falls. Interestingly enough, he and Tara Strong (who voiced Mary Jane Watson in Ultimate Spiderman) guest started in an episode of Pound Puppies 2010, with the latter playing a young girl named Dolores, and he played her father, who was in charge of a newspaper (though the character he voiced was much nicer, if slightly insensitive).
