Nicknamed The Tiffany Network, CBS has been looking more like Big Lots! of late.  But not last night.  Thanks to CSI and impressive showings for both Survivor and Without a Trace, CBS scored a Thursday prime time ratings’ win, according to Nielsen Media Research.  The Eye Web, yet another nickname for CBS, averaged 25.1 million viewers and a 7.9 ratings/20 share for the evening, among the coveted 18-49 demographic.

Not to worry American Idol fans.  Although CBS won last night overall, Idol remained Numero Uno in the 8-9 time slot.  And Simon’s still crying all the way to the vault.
