Impact of the COVID-19 pandemic
The ceremony was originally to take place at the Shrine Auditorium in Los Angeles, which was scheduled on March 29, 2020. On March 12, due to the state of California restricting gatherings to 250 people in response to the COVID-19 outbreak, which it had already declared a pandemic by the World Health Organization, and has cancelled scores of television events through March into July, along with postponing the ACM Awards and Billboard Music Awards. On the morning of March 16, iHeartMedia announced the ceremony's official postponement.

Half of the ceremony's original March 29 timeslot was retained by iHeartMedia, with both them and Fox then promoting a series of musical performances from several popular artists and bands performing from home via video and teleconferencing platforms compiled together as the iHeart Living Room Concert for America hosted by Elton John, along with charitable appeals for Feeding America and the First Responders Children's Foundation. The program also aired over a number of iHeartRadio stations nationwide, and was simulcast on Fox Sports 1/2, Fox Soccer Plus, Fox News Channel, Fox Business Network, the Big Ten Network, and Fox Deportes. On August 24, 2020, it was announced that the ceremony had been cancelled and that the winners would be announced through the iHeartRadio stations over Labor Day weekend.
