podfading
n.— «Podcasting has drawn thousands on the premise that anyone can create an audio program, build an audience online and even vault to stardom. Less celebrated is the fact that untold numbers of shows just wink out just as suddenly as they started. The phenomenon has earned its own label, “podfading,” coined by podcaster Scott Fletcher in February 2005 when he gave up on two podcasts of his own.» —“Podfading Takes Its Toll” by Steve Friess Wired News Feb. 7, 2006.
