I think the Grammys started to go downhill when the Starland Vocal Band beat out Tom Petty and the Heartbreakers for best new artist in the mid-seventies. :(
My jump the shark moment for the Grammys was when Milli Vanilli won for best New Artist. Then it turned out they neither sang or performed on any of those records!
It's just hard for the music to break through the attention whores pushing their personal and political agendas. He never even asked us to watch the show.
Not a very good marketing strategy.
