On November 1, 2005, Frederator launched what it called "the first cartoon podcast." Named Channel Frederator by David Karp (who also structured and edited the initial episodes), this weekly animation network features submitted films from around the world, and quickly became one of the top video podcasts on Apple Inc.'s iTunes. In quick succession, The Wubbcast was launched for pre-schoolers in January 2006, and "ReFrederator" featuring vintage public domain cartoons in April 2006. Channel Frederator became the model for Seibert's media company Next New Networks and reaches almost 4,000,000 video views monthly.
