Last year, we noted that Ticketmaster, who for years has based its business model on being a monopoly provider of event tickets, was so upset at the growing number of web-based competitors for reselling tickets that it was pushing for laws to make selling tickets above face value illegal in an effort to stop sites (or users of sites) like StubHub (an eBay subsidiary) and Craigslist from selling tickets. Apparently, the company also has a second plan: sue the competition. The company has sued StubHub for selling tickets to concerts where Ticketmaster claims it was supposed to be the "exclusive" ticket provider. The company claims it had signed contracts with certain venues to guarantee exclusivity. However, StubHub was (according to Ticketmaster) still able to get tickets to these venues by threatening that they "might not be considered as venues for future live-entertainment events." It's not clear why Ticketmaster is suing StubHub, however. If the venues broke a contract, why isn't Ticketmaster suing the venue? StubHub never signed an exclusivity contract with Ticketmaster. Also, StubHub seems to be selling the tickets at three to four times as much as Ticketmaster is selling the tickets, so it's not like people are likely to go to StubHub instead of Ticketmaster for those tickets.
