The Royal Rumble is a professional wrestling pay-per-view event, produced every January by professional wrestling promotion WWE. The initial event, however, was not a pay-per-view but was originally shown as a television special on USA Network. The following year's event was the first Royal Rumble pay-per-view event.
In March 2007, WWE announced that all subsequent pay-per-views would feature performers from all brands. Dates were slowly removed from the pay-per-view schedule, and in 2012 WWE returned to holding twelve pay-per-views a year. In 2009, WWE began to rename several of its B-show pay-per-views, identifying them with types of matches such as the Money in the Bank ladder match and the Hell in a Cell cage match.
