Hulk Hogan helped usher in the 1980s professional wrestling boom, where he headlined eight of the first nine editions (1, 2, 3, 5, 6, 7, 8, and 9) of the WWF's flagship annual event WrestleMania. Hogan also was a regular headliner of Saturday Night's Main Event and its spin-off The Main Event. During his initial run, he was a five-time WWF Champion, with his 1,474-day reign being the longest of the WrestleMania era ever. He was the first wrestler to win consecutive Royal Rumble matches, winning in 1990 and 1991. His match with André the Giant on WWF The Main Event on February 5, 1988, still holds American television viewership records for wrestling with a 15.2 Nielsen TV rating and 33 million viewers.
