Secondary ticket marketer StubHub has just entered into an exclusive multi-year agreement with NBC Sports Digital to become the official ticket provider for all of the NBC Sports Digital properties. The deal will give StubHub an integrated partnership with 12 NBC websites.

Among the sites that will now be partners will be NBCSports.com, NBC Sports Talk Blogs, Rotoworld.com as well as a number of the NBC regional networks such as CSNBayArea.com, CSNCalifornia.com, CSNWashington.com, CSNBaltimore.com, and SNY.tv.

There is some interesting synergy between the two companies. StubHub already draws strong interest from fans who are looking for tickets to sold-out events, or for ones that are expected to be poorly attended. Now fans watching an event on NBC and its family of heavily trafficked web sites might see a notice for an upcoming sporting event that is nearby and quickly look at StubHub to check on ticket pricing and availability.

Since it was launched 13 years ago StubHub has been slowly growing in reach as it has signed a number of powerful sports partners over the years. It is where teams and individuals can go and resell tickets for sporting events, and the games are all priced competitively versus rivals such as Craigslist and SeatAdvisor.

Included in its family of partners are over 60 teams in the NFL, MLB, NBA, NHL, MLS and NCAA, the San Francisco Giants and the University of Texas.
