NBC's football broadcast commands more than $200,000 more per 30-second spot than Fox's singing competition.

American Idol is no longer the most expensive show for advertisers.

NBC's Sunday Night Football has far surpassed Fox's singing competition in terms of ad rates, according to a survey in Advertising Age.

The two shows were effectively tied in last year's report -- with less than $10,000 separating them -- but for the 2012-13 season, SNF reportedly commands about $205,000 more per 30-second spot on average.

SNF's average cost to advertisers for the current season is $545,142, up from $512,367, Ad Age reported. Meanwhile, the Wednesday edition of Idol -- the performance episode -- fell from $502,900 last season to $340,825. Thursday's results show fell from $468,100 last season to $296,002, coming in at No. 5 on the Ad Age rankings.

While SNF has continued its ratings dominance -- last week, the broadcast pulled in a 6.9 rating with adults 18-49 and 17.7 million viewers -- Idol has seen its ratings drop off as the show ages and the judges panel undergoes shakeups.

This year saw the depatures of judges Steven Tyler and Jennifer Lopez, who had been with the show for two seasons, with Mariah Carey, Nicki Minaj and Keith Urban taking their places alongside veteran Randy Jackson.
