The Billboard Music Awards take a holistic look at artist performance based on key fan interactions with music -- finalists and winners are determined by chart performance and social and streaming activity as chronicled in Billboard magazine and on Billboard.com during the eligibility period of Feb, 28, 2010 and Mar. 1, 2011.

The 46 award categories are based on measures provided by Billboard's data partners including sales data shared by 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 2011 Billboard Music Awards is co-executive produced by Richard Beckman, CEO of Prometheus Global Media, which owns Billboard and The Hollywood Reporter, and Don Mischer of Don Mischer Productions.
