Robert, out of curiosity, is there any chance we will ever see a top 20 18-34 list, or are the numbers not available/demand isn’t there/ratings arn’t significant enough?
Which also brings up, how important is that younger side of 18-49 demo? I’m assuming that a network would prefer it’s 18-49 to lean younger, but would that skew ever help shows on the fence? Is 18-34 going to ever become to 18-49, what 18-49 became to total viewership?
Wow, Fringe really does have a loyal audience. It even beat Lost in the demo.
and The Mentalist, too.
SURVIVOR and ABC ROCKS!
Wow, great comeback of Fringe.
