2008 "to provide an exemption from exclusive rights in copyright for certain nonprofit organizations to display live football games", and "for other purposes". In 2004, the NFL started issuing cease-and-desist letters to casinos in Las Vegas that were hosting Super Bowl parties. "Super Bowl" is a registered trademark, owned by the NFL, and any other business using that name for profit-making ventures is in violation of federal law, according to the letters. In reaction to the letters, many Las Vegas resorts, rather than discontinue the popular and lucrative parties, started referring to them as "Big Game Parties". In 2006, the NFL made an attempt to trademark "The Big Game" as well; however, it withdrew the application in 2007 due to growing commercial and public relations opposition to the move, mostly from Stanford University and the University of California, Berkeley and their fans, as the Stanford Cardinal football and California Golden Bears football teams compete in the Big Game, which has been played since 1892 (28 years before the formation of the NFL and 75 years before Super Bowl I). Additionally, the Mega Millions lottery game was known as The Big Game (then The Big Game Mega Millions) from 1996 to 2002.
