For the first time in the history of the two long-running competitions, ABC's "Dancing With the Stars" outdrew both editions of Fox's "American Idol" last week.

Meanwhile, the broadcast networks faced ratings disaster on April Fools' Day that was no joke.

The Nielsen Co. said Tuesday that nearly 23 million people watched "Dancing" a week ago. An estimated 21.8 million people watched "Idol" on Tuesday and 20.5 million on Wednesday, Nielsen said.
