Silvercasting

From NY Times article, "As Internet TV Aims at Niche Audiances, the Silvercast is Born:"

"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.

In 2004, Wired magazine popularized the phrase "the long tail" to refer to the large number of specialized offerings that in themselves appeal to a small number of people, but cumulatively represent a large market that can be easily aggregated on the Internet. Plotted on a graph along with best sellers, these specialized products trail off like a long tail that never reaches zero."
