The "SpongeBob effect" refers to the fact that, as a result of Spongebob's massive success, if an animated show on Nickelodeon isn't immediately popular, it gets cancelled. The "Spongebob effect" can definitely be seen nowadays, with the bulk of the network's programming (not counting Nick. Jr.) being live-action shows. Do you think the network will ever go back to creating a variety of nicktoons like they did in the 90's and 2000's, or has the "Spongebob effect" completely ruined this possibility for the foreseeable future?
