What Broadcast Networks Are Getting From Advertisers For Each Primetime Show This Season

American Idol retains its status as the most expensive show on broadcast television for advertisers, despite a 9% dip in viewers between the ages of 18-49. Next year's "Idol" is getting an average $467,617 per 30-second ad on Tuesday night and $400,546 per 30-second ad on Wednesday's weekly results show, according to Advertising Age's annual TV pricing survey of media buyers, making "Idol" far and away the priciest show on TV for advertisers.

Fox dominates the list of top-dollar shows this year, in part due to the success of musical drama "Glee." Fox airs half of the top 10 most-expensive programs for the 2010-2011 season. NBC's "Sunday Night Football" continues its reign as the most-expensive program for advertisers for the first half of the TV season, commanding an average of $415,000 for a 30-second ad -- a testament to advertisers' fervent desire to align their commercials with live sports, where viewers watch in real time and can't fast-forward past the ads. For its part, "Glee" gets an average of $272,694 per 30-second ad in the fall, when it appears on Tuesdays, and $373,014 per 30-second ad in the spring, when it appears Wednesdays after the "Idol" results show.
