While the Screen Actors Guild Awards ratings have been flat for the last 5 years, the Grammy Awards ratings have been all over the map, presumably driven by the top award winners for that year. I wouldn't know, since as far as I'm concerned all the music the world ever needed was recorded between 1964 and 1968, in Detroit. (Although, even I knew that 1984 was the year of Thriller.)
*2006-2007 results are Live+SD, all previous years are Live viewing.
