The AMAs were created by Dick Clark in 1973 to compete with the Grammys after the move of that year's show to Nashville, Tennessee led to CBS picking up the Grammy telecasts after its first two in 1971 and 1972 were broadcast on ABC. Michael Jackson and Donny Osmond co-hosted the first award show with Rodney Allen Rippy and Ricky Segall in 1974.
While the Grammy Awards are awarded based on votes by members of the entertainment industry, the AMAs are determined by a poll of 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. The Grammys have nominations based on vote of the Academy and only nominate a work from their eligibility period that changes often.
