Ratings: NBC's Mr. Robinson Opens Well, Top Model Returns Steady

Leading out of the well-watched America’s Got Talent, NBC’s Mr. Robinson on Wednesday debuted to 4.6 million total viewers and a 1.2 demo rating, ranking as broadcast’s most watched summer comedy debut since 2007 (CBS’ Creature Comforts) and the No. 2-rated since 2009 (trailing only Undateable).

The series’ second half-hour however slipped to 3.8 mil and a 1.0. TVLine readers gave the comedy an average grade of “C-.”

AGT opened the Peacock’s line-up with 6.9 mil/1.4, slipping two tenths week-to-week but drawing the night’s largest audience. With a weaker lead-in, Last Comic Standing (3.7 mil/1.4) at 10 pm slipped 19 percent in audience and a tenth in the demo.

THE CW | Top Model opened Cycle 22 with 1.2 mil and a 0.4, matching its year-ago debut (on a Monday). A Wicked Offer, which apparently is something that aired, debuted to 720K/0.3.
