London 2012 Launches Sponsor Auction

London 2012 organizers today are launching a £250m online auction for outdoor advertising space around the Games. For the first two weeks, the auction will only be open to Tier I Olympic sponsors.

From The Guardian:

"In total about 4,000 packages of advertising will be up for sponsors and partners to buy – covering everything from billboards and posters right next to event sites to what is termed as "spectaculars" such as the Imax theatre on the Southbank as well as the London Underground."
