Ratings: Rats! Zoo Hits New Lows

CBS’ increasingly entertaining (if scientifically “iffy”) Zoo drew 5.8 million total viewers and a 0.9 rating this Tuesday, slipping 13 and 25 percent to hit new series lows.

NBC’s America’s Got Talent (10.7 mil/2.2) dipped 6 and 12 percent week-to-week yet easily led the night in both measures. Leading out of that, Hollywood Game Night (4.8 mil/1.3) ticked down a tenth.

Elsewhere, Fox’s 5th Grader (2.4 mil/0.6) and ABC’s Extreme Weight Loss (2.6 mil/0.7) both were flat.
