Starting 10 years ago, especially with RPG's, I've thought there should be a category in the Grammies for Video Game music (although the Oscar's have a best song category I don't think the Grammies have a best song in a movie category).
The only drawback would be that the awards would likely go to some Japanese made thing and forget about past greats like Stones or the technology of the Mockingboard.
But seriously, what other medium has revived interest in classical music other than video games?
