TV Ratings: ABC's 'Glass House' Cracks Under 'Big Brother' Comparison

ABC/NICOLE WILDER

If CBS is still feeling sour about ABC's Big Brother lookalike Glass House, the premiere ratings might ease the pain. The new reality offering entered the Monday lineup with a soft 1.6 rating among adults 18-49. Though Big Brother's most recent season did air on different nights (Wednesdays and Thursdays), its demo score outpaced the ABC premiere significantly, posting an average 3.2 adults rating over the course of last summer.

Topping the night, between 8 and 10 p.m. at least, was Fox. The pairing of Hell's Kitchen and MasterChef, though both down from the previous Mondays, won Monday with an average 2.4 rating among adults 18-49 and placing third among total viewers with 5.5 million. Individually, Hell's Kitchen dropped 11 percent for a 2.5 demo rating while MasterChef fell 15 percent for a 2.3 among adults.

NBC scored the night's strongest broadcast with America's Got Talent. Though at a season low, the two-hour episode hit a 2.8 rating among adults 18-49 and led into a solid American Ninja Warrior, down 9 percent but topping the hour among adults 18-49 with a 2.0 rating. Altogether, the network averaged a 2.3 adults rating and a dominant 7.6 million viewers.

Prior to Glass House, ABC aired an even Bachelorette, which posted a 2.3 rating among adults 18-49. The broadcast bled two minutes into House, so final ratings for the premiere could lose some steam. ABC placed third for the night in the key demo (2.0 rating among adults 18-49) and second among total viewers (6 million).

CBS was again in encores Monday night, averaging a 1.3 rating among adults 18-49 and 5.2 million viewers. The CW, also in repeats, posted just a 0.2 in the key demo and 465,000 viewers.
