Fox's 'Idol'-ized Emmycast demo-lished

Down 17% from '06, 18-49 numbers are worst ever

There was no "American Idol" ratings halo over Fox's coverage of the 59th Primetime Emmy Awards on Sunday.

According to early Nielsen data, the three-hour show hosted by "Idol's" Ryan Seacrest posted the lowest numbers ever for the awards show franchise among adults 18-49 despite being touted as a hipper revamp fronted by a young-skewing host. The 4.3 rating/11 share in the young demographic was down 17% from last year, when NBC carried the ceremony in August.

Things didn't look much brighter in total viewers, where the Emmys attracted 13.1 million, the show's smallest audience since 1990. That ceremony, also on Fox, drew 12.3 million viewers.

The Emmy Awards rotate among the Big Four broadcast networks each year.

The Emmys' ratings were impacted by NBC's "Sunday Night Football," which easily topped the awards show among adults 18-49.

Reliable ratings for the lopsided game between the New England Patriots and San Diego Chargers will not be available until Tuesday, but some estimates project a 5.6/14 in the 18-49 demo.
