I'm guessing the short version is "this route is much cheaper for MyNetworkTV"
Now that it's no longer a network, MyNetworkTV is out of the nightly ratings game.
Nielsen informed its clients Tuesday that MyNetworkTV has stopped supplying program information to its daily reporting service effective this week.
Instead, MyNetworkTV will now receive its numbers as part of the weekly syndication ratings report, which is released every Tuesday.
Move comes as MyNet officially morphed on Monday from a network into a programming service, airing off-net programming and movies as well as "WWE Smackdown" on Fridays.
