The Denver Broncos have one of the most storied franchises and fan bases in pro sports.
Since Pat Bowlen took over the team as owner in 1984, the Broncos have sold out an NFL-high 298 straight games and have the longest sellout streak in NFL history in one city, selling out 401 games over 49 years in Denver.
The Broncos regularly invade opposing team stadiums, especially when the team travels to face the Chargers. In 2018, the presence of Broncos fans was so strong at University of Phoenix Stadium against the Cardinals, it sounded like a home game for Denver.
