The new Tuesday 10 p.m. timeslot premiere of the CBS newsmag “48 Hours” fell below the slot’s average with “Dellaventura” and below the Thursday 10 p.m. average for the newsmag.While CBS wants to test “Dellaventura” at least one more time Thursday at 10 p.m., the Eye web is strongly considering moving “48 Hours” back to Thursday night, especially now that ABC is moving “20/20″ to Monday nights and is airing a movie Thursday instead. “48 Hours” scored a third-place 6.3 rating and 11 share in homes Tuesday and a 2.6 in adults 18-49. The newsmag was overshadowed by a special 90-minute episode of ABC’s “NYPD Blue,” which rated a 12.9/21 in homes and an 8.4 in young adults. Based on the strength of “NYPD Blue,” ABC won Tuesday night by a hair, with an 11.2/18 household average and a 7.2 in young adults. NBC was second with an 11.1/18 in homes and a 7.0 in young adults. ABC had considerably less luck in the 8 p.m. timeslot. ABC’s “Grace Under Fire” (7.3/12 in homes and 4.3 adults 18-49) received the lowest rating on record for an original entertainment program in the Tuesday 8 p.m. timeslot. “Grace” placed third in homes behind NBC’s “Mad About You” (10.3/17 and 6.5), which also hit its lowest rating ever in that timeslot, and CBS’ “Jag” (9.4/15 and 3.4), which placed fourth in young adult demos.
