My recent favorite startup story is featured on the Startup Podcast, Season 3, episodes 1 and 2. It's about a couple of just-out-of-college kids who start out with a totally dumb idea that goes through a couple of pivots over 5 years, and eventually cashes in for a billion dollars doing something that almost everyone would think is another dumb idea.
Check it out: scroll down to Season 3, episodes 1 and 2. A great story that clearly illustrates the value of the pivot and perseverance.
