I watch South Park at least once a day.. it's my favorite show. It's an American adult animated sitcom. 
where does it air? what else can you tell me about it
It airs in Comedy Central, and it's one of their most highest rated shows. They're also going to air new episodes through 2019.
oh, how many episodes have they done ?
A ton! They've been around since August of 1997, and they've had major success. They consistently earn the highest ratings of any basic cable program.
