The Awards' finalists and winners were determined by a combination of chart performances and social and streaming activity as chronicled in Billboard magazine and on during the eligibility period of February 28, 2010 through March 1, 2011.

The forty-six award categories were based on measures provided by Billboard's data partners including sales data from Nielsen SoundScan, radio airplay monitored by Nielsen BDS, streaming data measured by Tubemogul and Nielsen BDS, social media consumption gauged by Next Big Sound and tour grosses tracked by Billboard Boxscore.

The awards show took place at the MGM Grand Garden Arena in Las Vegas, Nevada in partnership with Chevrolet and the Las Vegas Convention and Visitors Authority (LVCVA).

This is the first year that ABC broadcasted the event and marks the first Billboard Music Awards show since 2007.
