The first prominent use of the Adobe Flash animation format was by "Ren & Stimpy" creator John Kricfalusi. On October 15, 1997, he launched "The Goddamn George Liquor Program", the first cartoon series produced specifically for the Internet. The series starred George Liquor (a fictional character rumored to have ended Kricfalusi's employment on "Ren & Stimpy") and his dim-witted nephew Jimmy The Idiot Boy. Later, Kricfalusi produced more animated projects with Adobe Flash Professional including several online shorts for Icebox.com, television commercials, and a music video. Soon after that, web cartoons began appearing on the Internet with more regularity.
