From South Park Blog:
Hulu and South Park Digital Studios announced today the exclusive, multi-year licensing agreement to stream all seasons of “South Park” on the Hulu Plus subscription service. In addition, the entire “South Park” library will be available for free on Hulu from now until the premiere of season 18 this fall (Sept. 24). Fans will have next-day access to new episodes on Hulu and Hulu Plus starting with season 18. SouthPark.cc.com will continue to have all seasons of South Park until the beginning of season 18, at which point both Hulu and SouthPark.cc.com will have a revolving selection of free episodes available. Hulu will power the video and advertising experience on SouthPark.cc.com.
As of now until September 24, 2014 all but a few select episodes of South Park (Super Best Friends, 200 and 201) are freely available for viewing. Thereafter “a revolving selection of free episodes” will be available for viewing at Hulu and SouthPark.cc.com.
“This is a natural partnership for us,” said Matt Parker and Trey Stone, creators of “South Park.” “We are excited that the entire library will be available on Hulu and that the best technology around will power South Park Digital Studios.”
Does that mean Super Best Friends, 200 and 201 will be available for viewing to Hulu Plus subscribers?
It seems that South Park episodes will be heavily pirated again in the United States.
