Washington - Ted Leonsis, the vice chairman emeritus of AOL and a well-noted film buff, on Thursday launched his new documentary site, known as SnagFilms. The DC-based company, also backed by AOL co-founder Steve Case and venture capitalist Miles Gilburne, said that it aims to address the "bottleneck" in documentary distribution that "has left many great films unable to reach their potential audience or to provide a viable financial return."
