With another big showing last night, Glee has become the highest-rated new scripted series this season. The high-school musical dramedy averaged a 5.3 rating/14 share among adults 18-49 after American Idol, flat from last week’s heavily promoted Madonna episode. Also on a positive note, airing against Glee at 9 PM, CBS’ NCIS: LA logged a 3.2/8 in 18-49, up 7% from the show’s last original on April 6.

But last night also marked season lows for juggernauts Idol (6.6/19 for a Tuesday edition), Dancing (2.3/7) and CBS’ NCIS (3.4/10). And, in bubble show watch, freshman ABC drama V, following a Lost repeat at 10 PM, hit a series low with a 1.9/5, down 14% from last week.

The 10 PM “freshman” hour, as it pits against each other rookies V, The Good Wife and Parenthood, NBC’s Parenthood (2.4/7, 5.9 million viewers overall) faced an original of CBS’ Wife (2.2/6, 12.1 million) for the first time in three weeks. The NBC family dramedy was down 17% from last week but still won the hour in the demo, while Wife was tops in total viewers. With Idol and Glee, Fox (5.9/16, 15.7 million) won the night in adults 18-49 and total viewers.
