Networks and advertisers love the 18 to 49 demographic. If you're not in that demo, then just sell your TV right now, OK? Nielsen even creates an "awareness" survey every year and sends it to the networks so they know which new shows have made it into the public consciousness, and Nikki Finke has the list.

ABC's Flash Forward and The Cougar have the most awareness, while Hank has the lowest (every time I hear the name of this show I forget that Kelsey Grammer is in it - it sounds like the name of an animated show).
