The University of Phoenix has received media exposure worth as much as $20 million from its naming rights sponsorship of the Glendale, Ariz., stadium where Super Bowl XLII unfolded, according to Joyce Julius & Associates.

The Michigan firm that measures the impact of corporate sponsorship figures the actual game broadcast generated a value of $10.2 million from the 1 minute and 33 seconds of time the online university's name appeared on screen and two announcer references to it. That’s measured against the average $2.7 million companies paid for 30-second ads that aired during the game broadcast.

The firm says the university got another $6 million worth of exposure from media stories and another $4.5 million of exposure from hosting the BCS national championship game last year.

The $10.2 million game exposure is down from $13.6 million for Ford when the game was played at Ford Field in Detroit in 2006 and up from the $2.1 million for Alltel, when the game was played at Alltel Stadium in Jacksonville in 2005, Joyce Julius reported.
