NBC’s America’s Got Talent (2.6/9 in 18-49, 11.3 million viewers from 8-10:01 p.m. ET) continues to dominate Tuesday nights, retaining 100% of last week’s demo rating –  though that had been the franchise’s smallest tally so far this edition. Talent won the time period among ABC, CBS, NBC and Fox in every key measure, and grew steadily throughout its two hours, by 32% in 18-49 the demo and nearly 2 million overall viewers. After Talent, Night Shift slid 7% (1.4/5, 6.6 million viewers).

CBS’ NCIS (0.9/3, 7.8 million viewers), NSIC: LA (0.9/3, 6.3 million viewers), and Person of Interest (0.8/3, 5.2 million viewers) all were repeats, but managed to finish No. 2 in their slots. ABC’s Tuesday slate should probably get a pass, since it was scheduled on short-ish notice, after the NBA Finals concluded Sunday night and made a Tuesday Game 6 unnecessary. That said, two hours of original Extreme Weight Loss logged a third-placed 0.8/3 (3.0 million viewers) at 8 PM and 0.8/3 (2.7 million viewers) at 9 PM.

Fox’s Family Guy repeat (0.8/3, 1.7 million viewers) was competitive at 8 PM – far less so the network’s live-action comedy reruns that followed, including back-to-back Brooklyn Nine-Nine episodes (0.4/2, 1.0 million viewers and 0.5/2, 1.2 million viewers) and The Mindy Project (0.4/1, 1.1 million viewers).

CW’s Famous in 12 (0.2/1, 628,000 viewers) — in which one lucky family seeks fame in 12 weeks with the help of TMZ — plunged 33% from previous week. From that lousy launchpad,  Supernatural (0.3/1, 704,000 viewers) clawed its way up a notch.
