Last year, the highest honors in the music industry were watched by 19.9 American television viewers.
Performers on the live telecast also paid tribute to basketball star Kobe Bryant, who was killed in a helicopter crash hours before the Grammy show took place in the venue that is home to his former team, the Los Angeles Lakers.
