The NBA announced an aggressive move in the ticket landscape Monday, joining forces with Ticketmaster to create the sports world's first website that will list tickets for games sold by both teams and fans.As fans and brokers have taken to the secondary market to resell tickets, many teams have felt left out of the game, as secondary ticketing sites like StubHub get a percentage from the buyer and the seller.In one recent survey, the NBA found that 70 percent of fans who had purchased tickets from a secondary site went to the team site first and didn't find what they were looking for. Another survey reflected that two out of every three fans wanted to shop for their tickets in only one location. Source: ESPN
