From a MyNetworkTV press release:
– For the second week in a row, “WWE Friday Night SmackDown” becomes the highest rated telecast inMyNetworkTV history, topping last week’s HH ratings by +11% (1.9 to 2.1). Nearly 3.5 Million Total Viewers tuned in, an increase of 287,000 (+9%) over last week’s Premiere.
– MyNetworkTV delivers the biggest A18-49 ratings & viewers (1.1 rating / 1.5 Million) in network history.
– For the second week in a row, MyNetworkTV finishes #1 in M18-34 (1.3 rating) topping all other broadcast networks for the night.
– On Friday 10/10, MyNetworkTV more than doubles the amount of the CW’s Total Viewers for the night (3.5 Million vs. 1.6 Million). In A18-49 MyNetworkTV bests CW by 57% in ratings (1.1 vs .7)

so…why are we counting CW and not MyNetwork TV?
Jonthemon, on our part it is because we do not see overnight ratings for MNT and do see them for the CW. As MNT grows, that may change — we do see ratings for its shows on a weekly basis but outside of Smackdown, the numbers are still pretty small.
