"Lost" loses steam in the ratings

The fifth season-premiere of Lost didn’t gain viewers as the event notched its lowest-rated season-premiere to date.

Lost averaged a 5.0 rating and 12 share among adults 18-49 and drew 10 million viewers for ABC in the 8-10 p.m. (Central) time slot Wednesday night for ABC. While the results were still pretty good, it’s still down from the fourth-season premiere in 2008 (which aired on a Thursday) and Lost viewers every half-hour, never a good sign (excuse the pun.)

By comparison, American Idol drew 25 million viewers and a 9.6/25 in 18-49s for Fox on Wednesday.

Locally, Lost averaged a surprisingly low 5.8/9 in households for WLS-TV (The highest-rated market for Lost was Detroit, where WXYZ-TV earned a 10.1/15.)

By comparison, WLS’ 10 p.m. newscast on Tuesday earned a 13.4/22 in households.
