Bowls through Super Bowl LIX, the soonest that any stadium outside the NFL's footprint could serve as host would be Super Bowl LX in 2026. Eight stadiums that hosted at least one Super Bowl no longer exist: Tulane Stadium, on the Tulane University campus, which hosted three Super Bowls, was demolished in November 1979. Tampa Stadium, which hosted two Super Bowls, was demolished in April 1999. Stanford Stadium, which hosted one Super Bowl, was demolished and redeveloped in 2005–06. The Orange Bowl, which hosted five Super Bowls, was demolished in May 2008. The Hubert H. Humphrey Metrodome in Minneapolis, which hosted one Super Bowl, was demolished in March 2014. The Georgia Dome in Atlanta, which hosted two Super Bowls, was demolished in November 2017. The Pontiac Silverdome in suburban Detroit, which hosted one Super Bowl, was demolished in March 2018. San Diego Stadium, which hosted three Super Bowls, closed in March 2020 and was demolished in early 2021. Super Bowl trademark The NFL very actively seeks to prevent what it calls unauthorized commercial use of its trademarked terms "NFL", "Super Bowl", and "Super Bowl Sunday". As a result, many events and promotions tied to the game, but not sanctioned by the NFL, are asked to refer to it with euphemisms such as "The Big Game", or other generic descriptions. A radio spot for Planters nuts parodied this, by saying "it would be super... to have a bowl... of Planters nuts while watching the big game!" and comedian Stephen Colbert began referring to the game in 2014 as the "Superb Owl". In 2015, the NFL filed opposition with the USPTO Trademark Trial and Appeal Board to a trademark application submitted by an Arizona-based nonprofit for "Superb Owl". The NFL claims that the use of the phrase "Super Bowl" implies an NFL affiliation, and on this basis the league asserts broad rights to restrict how the game may be shown publicly; for example, the league says Super Bowl showings are prohibited in churches or at other events that "promote a message", while venues that do not regularly show sporting events cannot show the Super Bowl on any television screen larger than 55 inches. Some critics say the NFL is exaggerating its ownership rights by stating that "any use is prohibited", as this contradicts the broad doctrine of fair use in the United States.
