According to the History Channel's brand new Foursquare page, the initiative was concocted to promote America, The Story of Us, "an epic 12-hour television event that tells the extraordinary story of how America was invented. It is an intensive look at the people, places and things that have shaped our nation, and the tough and thrilling adventure that is America's 400-year history."
Users will also be automatically entered into a concurrent sweepstakes, in which 10 randomly selected users will win prizes each week from April 25 through June 6.
Foursquare inked this deal back in February as part of a larger string of partnerships with big media brands. Zagat, Warner Bros and HBO all committed to Foursquare campaigns around the same time as the History Channel.
