[http://active.typepad.com/.shared/image.html?/photos/uncategorized/golf_1.jpg]Ten years ago the Golf Channel was launched despite many in the TV sports industry saying it had no chance.

But a decade later it now grosses 100 million dollars of ad revenue-- trailing just behind ESPN and FSN in that category. (Sports Biz has an interesting post on this.)
