TV Ratings: 'Big Brother' Tops Steady Summer Thursday
Thursday night was crowded for broadcast — though only during the 9 o'clock hour.
All five of the networks aired originals, with an even Big Brother nabbing the top spot with a 1.8 rating among adults 18-49 and 6 million viewers.
ABC's Greatest Hits came in at No. 2 with a 1.0 rating in the key demo, followed by NBC's Spartan (0.9 adults), Fox's Home Free (0.5 adults) and the CW's Beauty and the Beast (0.2 adults).
Primetime also saw a new BattleBots (0.9 adults) on ABC and, at 10 p.m., Aquarius was wildly improved (but still very low) with a 0.5 rating among adults 18-49 on NBC.
