The Mr. America contest is a bodybuilding competition started by the Amateur Athletic Union (AAU). It was first held on July 4, 1939, and the winner was named "America's Best Built Man". In 1940 this was changed to what is now known as the Mr. America contest. In the mid-1940s, Joe and Ben Weider started the IFBB as an alternative to the AAU. They held their opposing contest, the IFBB Mr. America, in 1949 and then from 1959 through 1977. Rights to the Mr. America name have been sold several times after AAU discontinued holding the contests in 1999.
