After 15 seasons on Comedy Central, “South Park” creators Trey Parker and Matt Stone took Broadway by storm this year with a little show called “The Book of Mormon,” which swept the Tonys and became a box office juggernaut.

Over the years, Parker and Stone have established a rep as particularly fan-attentive creators, going out of their way to cater to the big, broad demo that’s the foundation of their success. This year that’s evidenced in “The Year of the Fan,” a “South Park” initiative that has included such enthusiast-bait as a pop-up version of South Park (the town) at Comic- Con, as well as an unheard-of, one-time-only free perf of “Mormon” for an audience of lottery-selected fans.

The duo also has staked out a strong online presence for the show’s content, releasing “South Park” episodes soon after they air via ad-supported streaming video. “It’s about creating content that fans will like and making sure it’s available to them on all the platforms they want to watch it on,” says Comedy Central prexy Michele Ganeless. “We want to make sure our fans get ‘South Park’ from us, and not from someone else.”
