he fifteenth season of the American animated sitcom South Park began airing on Comedy Central on April 27, 2011 and ended on November 16, 2011. In response to reactions to the mid-season finale episode "You're Getting Old", which seemed to insinuate that creators Trey Parker and Matt Stone were wrapping up the series, Comedy Central proclaimed through the media that South Park was renewed for two more seasons, and the duo were signed through 2013. Shortly before the airing of the season finale episode "The Poor Kid", South Park was extended again until 2016, taking the show to 20 seasons.
