The American Music Awards (AMAs) is an annual American music awards show produced by Dick Clark Productions since 1974. From 1973 to 2005, both the winners and the nominations were selected by the members of the music industry, based on commercial performance, such as sales and airplay. Since 2006, winners have been determined by a poll of the public and fans, who can vote through the AMAs website. The event originally aired on American Broadcasting Company, after the network's contract to air the Grammy Awards expired. CBS will air the 2024 edition.
