The New York Times writes about slivercast:
In the last six months, major media companies have received much attention for starting to move their own programming online, whether downloads for video iPods or streaming programs that can be watched over high-speed Internet connections.
Perhaps more interesting and, arguably, more important are the thousands of producers whose programming would never make it into prime time but who have very dedicated small audiences. It’s a phenomenon that could be called slivercasting.
Indeed, the Internet’s ability to offer an almost infinite selection is part of what makes it so appealing: people can find things that don’t sell well enough to warrant shelf space in a neighborhood music store or video rental shop think of the obscure books on Amazon.com. The ease of digital video production and the ubiquity of high-speed Internet connections are sending the long tail of video into the living rooms of the world, live and in color.
