With most of its competition in repeats, Fox’s “Glee” hit a season high last night, dominating what’s become one of the most competitive slots on broadcast.

“Glee” averaged a 3.6 adults 18-49 rating, according to Nielsen overnights, its best rating this season and up 13 percent over its season average of 3.2.

The reason for the bump wasn’t hard to gauge. It was the least competitive Wednesday night in months, with ABC’s “Modern Family” and “Cougar Town” and NBC’s “Law & Order: Special Victims Unit” in reruns and CBS preempting usual timeslot winner “Criminal Minds” for a Grammy nominations special.

CBS was first at 8 p.m. with a 3.8 for “Rudolph,” followed by Fox with a 2.3 for “So You Think You Can Dance.” ABC was third with a 1.9 for a “Modern Family” rerun and a new “The Middle” (2.0), NBC fourth with a 1.8 for “Christmas in Rockefeller Center,” Univision fifth with a 1.4 for “El Nombre del Amor” and CW sixth with a 0.4 for a repeat of “Gossip Girl.”

Fox took the lead at 9 p.m. with a 3.6 for “Glee,” while CBS slid to second with a 2.3 for “Grammy Nominations Concert Live!” ABC and NBC tied for third at 2.0, ABC for repeats of “Modern” and “Cougar” and NBC for an “SVU” rerun, with Univision fifth with a 1.7 for “Sortilegio” and CW sixth with a 0.5 for a repeat of “The Vampire Diaries.”
