Michael Learmonth of Silicon Alley Insider has a great post on “Special Delivery,” a popular MySpace-sponsored hidden camera show that is a huge success on MySpace (in part thanks to promotion there), and a total flop on YouTube, where the show also has a channel. This attests to a common refrain we say a lot around here (because it’s true): since each video sharing site has different demographics and promotional opportunities, distribution to multiple sites not only increases viewership, but also helps in finding an audience and starting to build a community around content.
