This year’s Billboard Music Awards will be broadcast live from the Dolby Theatre in Los Angeles on October 14 after being pushed back from its original slot of April 29 due to the pandemic.
Singer Kelly Clarkson is on hosting duties. Fan-voted categories this year include Billboard chart achievement award and top social artist, with voting being made available on social media platform TikTok.
The Billboard Music Awards will be the latest major ceremony to take place post-Covid-19.
Many, including June’s BET Awards and August’s MTV VMAs, have relied heavily on pre-taped segments to navigate problems caused by filming during a pandemic.
However, the Emmys took place on Sunday with a fully live broadcast and earned widespread praise.
It is unclear what form the Billboard Music Awards will take but it is all but certain health guidelines in Los Angeles County will rule out an audience.
