The announcement confirms Dairy Queen's previous pledge, and doesn't draw down the remaining $12.5 million the university must raise privately for the project.
The deal gives the Edina-based company advertising rights to the stadium's scoreboard and electronic signs. The club room will also be named for Dairy Queen. Gopher football coach Tim Brewster welcomed the sponsorship agreement.
"To be able to form a partnership with such a tremendous organization -- I think about apple pie, lemonade and Dairy Queen. Is there anything more American that Dairy Queen?" said Brewster.
Dairy Queen is also giving $250,000 to the U of M's Carlson School of Management.
The university's private fundraising goal for the staidum is $86 million by the end of 2008. The total cost of the stadium is $288 million.
