From "Zap2it":

The return of "Jericho" (in repeat form) drew a 3.2/6 at 9 p.m., good enough to keep CBS in the lead. "Smackdown!" moved up to second with a 3.0/6. "Las Vegas" rolled a 2.5/5 for NBC. "Standoff" was fourth for FOX, ahead of the 1.8/3 for "Kyle XY" on ABC.

Now I'm not sure how these rating systems work, because I don't think 3.2 is the millions of people watching.

However the only people who are usually watching TV on friday nights are older couples, and not alot of the other viewers, in my opinion.

That said, this is good news for Jericho. A show that's able to keep CBS in the lead on friday night and make CBS the winner for the night should impress network executives.
