Hogan began his professional wrestling career in 1977, but gained worldwide recognition after signing for World Wrestling Federation (WWF, now WWE) in 1983. There, his persona as a heroic all-American helped usher in the 1980s professional wrestling boom, where he headlined eight of the first nine editions of WWF's flagship annual event, WrestleMania. During his initial run, he won the WWF Championship five times, with his first reign being the second-longest in the championship's history. He is the first wrestler to win consecutive Royal Rumble matches, winning in 1990 and 1991. His match with Andre the Giant on WWF The Main Event on February 5, 1988, still holds American television viewership records for wrestling with a 15.2 Nielsen rating and 33 million viewers.
