Since 1970, Boise State has played its home games in Albertsons Stadium (known as Bronco Stadium from 1970 to May 2014), which enjoys a reputation as one of the most difficult places in the country for opposing teams to play. The stadium is well known for its blue artificial surface, which was first installed in 1986 making it the first college stadium field to be any color other than traditional green, as well as the only college to have a non-green field for 22 years (1986–2008). “The Blue,” as it is called by fans, is one of the most distinguishing and enduring symbols of Boise State football. Boise State holds a trademark on any non-green field, not just blue. Therefore, anyone (high school, college, or otherwise) must apply for a license from Boise State before installing a football field any color other than green.
