I think that the American Idol, The Voice and other glamorized talent shows can really open the door for artist in today's market. Everything we do is so "now", got to go, catch a bite/byte here or there, so you only have a moment to make a first impression. Exposure like this should do wonders for GPN... heck look what happened in Dec 2010 with the VHS Diva's show. 
I think shows like Glee have helped save the careers of many artist or at least gave them a much needed boost. I think there is still hope in the world when I hear my 18 year College Freshman's playlist: Queen, Credence, Aerosmith, Journey mixed in with today's often misaligned electro/techno auto tune imposers.
