Silvercasting vs Goldcasting

A while back a New York Times article referred to the networks streaming of less well known content "silvercasting."

From the article: (subscription required)

"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."

With ABC streaming its 4 best shows, have we found "goldcasting?" I think it makes sense as more and more people become accustom to viewing video online that the major players would open up both types of content channels.
