Aided by tropical storm Hanna which disrupted both CBS's US Tennis Open (I believe *some* of which ran, but am not certain how much) and ABC's NASCAR coverage (which was moved to Saturday, I'm not sure what ran in its place), Fox won both the viewership (5.31 million) and adults 18-49 demo (1.8 rating / 6 share) titles easily with the season premiere's of its crime reality duo Cops and America's Most Wanted.
Cops averaged 5.27 million viewers and a demo 1.9/6 and America's Most Wanted 5.34 million viewers and a demo 1.8/5 to top both o their hours.
NBC, without tropical storm effects, went with reruns and finished second for viewers with 3.66 million and ABC was second for the demo with a 1.0/3,

Fast Affiliate Overnight Ratings: Local metered-market ratings service of Nielsen Station Index (NSI) in which household ratings and shares are provided to clients the morning following the day or evening of telecast. While routinely used for "next day" immediate analysis, these fast affiliate ratings are by process inaccurate for programs that air live across a network since they represent affiliate time period performance. For example, last night's 10-11pm affiliate #'s would reflect 10pm on the East Coast but also 10pm on the West Coast which for a live event would not represent the same broadcast or portion of the broadcast.
Rating: Estimated percentage of the universe of TV households (or other specified group) tuned to a program in the average minute. Ratings are expressed as a percent.
Share (of Audience): The percent of households (or persons) using television who are tuned to a specific program, station or network in a specific area at a specific time. (See also, Rating, which represents tuning or viewing as a percent of the entire population being measured.)
LIVE+SD: The number that watched a program either while it was broadcast OR watched via DVR on the same day [through 3AM the next day] the program was broadcast.
