The 57th annual Grammy Awards hit a low note in the ratings Sunday night, which saw the telecast utterly dominate broadcast rivals while slipping in popularity from recent years. The Grammys had 25.3 million viewers and a 8.5 rating among adults 18-49, down 11 percent in viewrs and 14 percent in the adult demo (in fact, it was the show’s lowest demo rating in six years).
