CBS’ “Person of Interest” aired its series finale with little fanfare on Tuesday night, with the fan-favorite procedural bowing out with a 1.0 rating in adults 18-49 and 6.5 million viewers, in line with its last two outings. The night also saw dips for NBC’s “America’s Got Talent” and “Maya and Marty,” and ABC’s “Uncle Buck.”

Despite the ratings drop, NBC still won Tuesday night, with “AGT” and “Maya” standing as the top two shows in the adults 18-49 demographic. “AGT” easily outpaced its rivals with a 2.3 rating and 11.5 million viewers from 8-10 p.m. — its only original competition in the 8 p.m. hour was Fox’s “Hotel Hell,” which notched a 0.8 rating and 2.6 million viewers. At 10 p.m. “Maya and Marty” scored a 1.1 in the demo and 4.4 million viewers, beating the “POI” finale for a timeslot win in a show that featured a “Broadway for Orlando” all-star performance of “What the World Needs Now Is Love.”

Behind a night of repeats, ABC’s “Uncle Buck” (1.0 rating, 3.7 million viewers) dropped a half point from last week’s premiere — which benefited from an original lead-in with the premiere of “To Tell the Truth” — but still came second in the 9 p.m. hour behind “AGT,” easily besting Fox’s “Coupled” (0.5 in the demo, 1.4 million viewers) and The CW’s “Containment” (0.3 rating, 1.2 million viewers). At 10 p.m., “To Tell the Truth” scored a 1.0 rating and 4.4 million viewers, tying with “Person of Interest” for second place in the demo.
