Young viewers just don't watch The O'Reilly Factor like they used to. April marked Bill O'Reilly's lowest-rated month in the 25-54 demographic since August 2001.

His 415,000 demo viewers in March was a new low, but O'Reilly managed to lose a few more in April, averaging 412,000 in the demo. Here's his post-Katrina track:

Sept: 1,115 / Oct: 518 / Nov: 468 / Dec: 460 / Jan: 472 / Feb: 458 / Mar: 415

But this trend started long before the hurricane. for O'Reilly, April's numbers reflected his lowest demo rating in almost five years.

Among total viewers, O'Reilly delivered a respectable 2,102,000 million viewers for the month. But that, too, was low -- the lowest, in fact, since July of 2004 (when he had 2,042,000). Click continued to feast your eyes on O'Reilly's monthly averages since 2001...

> Update: 7:03pm: An e-mailer says: "O'Reilly has had over two million people watching his show consecutively for almost a year? That's astounding. My question for you is, who has beaten O'Reilly in that 25-54 demo? Unitl somebody does, his lower #'s probably reflect less news than last year. He's still the undisputed king."
