created by Dick Clark in 1973 for ABC when the network's contract to present the Grammy Awards expired
Unlike the Grammys, which are awarded on the basis of votes by members of the Recording Academy, the AMAs are determined by a poll of the public and music buyers.
The American Music Awards have nominations based on sales, airplay, activity on social networks, and video viewing and can nominate only the works released between 1 December of the previous year and 1 September of the current year. Before 2010 had nominations based only on sales and airplay and nominated every work, even if old.
