To the media, there was only one Roller Derby, and from Jerry Seltzer's takeover in the late 50's the game reached new heights of popularity with a 120-station television network where taped games from the Bombers' home, Kezar Pavilion in San Francisco, were shown weekly. Television made fans of thousands and the Bombers packed arenas from coast to coast on cross country tours, regularly selling out arenas such as Madison Square Garden, Boston Garden, Kiel Auditorium in St. Louis and dozens more. The indoor record for Roller Derby was set at 19,507 at Madison Square Garden in 1970; it was broken by the outdoor record at the Oakland Coliseum a few months later at around 28,000 for a game between the Bombers and the Northeast Braves. The following year that record was topped again with 34,000 for a Bomber game at the Coliseum; their rival, the Midwest Pioneers, broke that record with 50,000 fans in 1972 for a game at Comiskey Park in Chicago. At this point, the Bombers home-team concept was duplicated with the New York Chiefs representing the Eastern U.S. and the Pioneers based in Chicago (but really everything west of Philadelphia).
