Nielsen Media Research told Adweek yesterday that they will be providing ratings information on commercials that are aired on all the five broadcast networks and on cable, starting this fall.

Previously, ratings were just provided for the programs themselves, but last fall, the networks requested that Nielsen provide average ratings for all paid national ads for each program aired. The ratings will be based on live views and seven days of DVR playbacks, a method that is currently under debate by advertisers during the network upfront ad-buying period.

If the networks like the results, they will use the numbers as part of their basis for setting ad prices in the 2007-08 season.
