Cable’s longest-running animated series South Park is headed for the 20-season mark. Trey Parker and Matt Stone, the creators of the no-holds-barred animated comedy, have closed a new deal with Comedy Central for three more seasons of South Park. The pact will keep the series on through 2016, extending its run to 20 seasons. Parker and Stone will continue to write, direct and edit every episode of South Park, as they have since the series’ premiere in 1997. “The collective genius of Matt and Trey knows no bounds,” Comedy Central’s president Michele Ganeless said. “Week after week and season after season they continue to surprise and delight South Park fans, and that includes all of us here at Comedy Central. We’re thrilled that the adventures of Stan, Kyle, Kenny and Cartman will continue through 2016.”
