Mashable's Brian Anthony Hernandez is at the YouTube Music Awards at New York City's Pier 36. Follow his live coverage on Twitter (@BAHjournalist) and Instagram (@BAHjournalist). He will be in the press tent interviewing winners.
Unlike other awards shows, the YTMA has only six categories (see list of nominees, below), some of which are unique to the event, such as the Response of the Year category, which recognizes the best covers, remixes and parodies.
YouTube chose its nominees based on musicians' YouTube stats, including video views, Likes, comments and channel subscriptions. The winners will be decided by share counts for each artist's nomination video on Facebook, Google+ and Twitter.
Musician Reggie Watts and actor Jason Schwartzman will host the show, and YouTube is airing pre-taped and live performances from New York, London, Moscow, Seoul and Rio de Janeiro prior to the show.
Here is the list of nominees in the six categories:
