The Napster company had quite a rocky start as the location where music enthusiasts could find each other and, using Napster’s amazing technology, exchange their music collections over the Internet.   No money ever changed hands.  In a way, it was just like selling bootleg compact discs except that nobody made any income from it.  In fact, it was the free part of the model that perturbed the recording artists and record labels.  Eventually Napster settled with the recording industry, with a huge financial award.  They learned their lesson well enough to completely change their business model.
