The Wednesday night debuts of ABC’s “The Evidence” and NBC’s “Heist” at 10 p.m. (ET) couldn’t overtake CBS’s veteran in the time slot, its franchise drama “CSI: NY.”

“Evidence” scored a 3.4 in adults 18 to 49, a number that included live-plus-same-day viewing, according to Nielsen Media Research. That was 11 percent below the time period average of the season’s previous time period holder, “Invasion” (3.8).

On NBC “Heist” scored a 3.0 in the demo, down 17 percent from the seasonal time slot average of time period holder “Law & Order,” which scored an underwhelming 2.6 in its temporary time slot at 9 p.m.

“CSI: NY” beat both 10 p.m. newcomers with a 4.4.

Fox scored with the post-“American Idol” debut of its new reality series “Unan1mous” at 9:30 p.m., hitting a 7.1 in the demo, tying for first place with ABC’s “Lost” in the half-hour.

CBS’s new 8 p.m. comedy block “Out of Practice” (2.0) and “Courting Alex” (1.7) garnered less than half their time period averages on Mondays at 9:30 p.m., a time slot both sitcoms occupied at different times this season. The No.1-rated show in the 8 p.m. hour was NBC game show “Deal or No Deal” with a 5.1.

The top-rated show at 9 p.m., “American Idol” (11.4), also easily took the No. 1 spot for the night among all shows among adults 18 to 49.
