Carsey-Werner’s “You Bet Your Life” stuck at the same level as its first week in national syndication according to Nielsen rankings for Sept. 21-27, while “The Wonder Years” and “Designing Women” led a roster of premiering off-network programs.The Bill Cosby gameshow is the most prominent of this fall’s new firstrun entries and is thus far performing well below advertiser projections, with rival syndicators predicting that the show could face time-period downgrading if it doesn’t improve during the November sweeps. Among other new firstrun strips, Multimedia’s latenight talker “Rush Limbaugh” (with a 2.7 rating) improved by 8% over its premiere numbers while Genesis’ “Whoopi Goldberg Show” (2.4) dropped a tick off its first week. Paramount’s “The Arsenio Hall Show” drew a 2.8 rating. Among established access shows, Twentieth TV’s “A Current Affair” also rebounded off last week’s subpar performance, improving by 10% after finishing behind King World’s “Inside Edition” for the first time during the Sept. 14-20 period. As for new off-network offerings with a barter advertising element, “The Wonder Years” (3.7) premiered with pretty good numbers on 125 stations covering 84% of the U.S., while national numbers for “Designing Women” were being re-processed (likewise for “The Montel Williams Show”), although Columbia Pictures TV reported a 5.5 average rating in metered markets on the sitcom. The Warner Bros. Domestic TV Distribution-Fox Children’s Network alliance also continues to look strong, with “Batman” nabbing a 4.4 rating in households and 7.7 among children age 2-11, both tops in that genre, followed by lead-in “Tiny Toon Adventures” (3.9, with a 7 among kids). Buena Vista TV was up next with its new strip “Goof Troop,” marching to a 3.6 and 6.8, respectively. Columbia’s shared cable-syndicated entry “Beakman’s World” also premiered as a weekly series that week with a 3.7 rating, cleared in 98% of the U.S., corralling the highest rating for any weekly kidvid show. New action hour “Renegade” also chased down credible numbers with a 3.8 rating on 121 stations covering 91% of the U.S., a tenth off the rating for companion-hour “Street Justice,” which enjoys the same national coverage. Paramount’s “Star Trek: The Next Generation” beamed up terrific numbers, meanwhile, including a stellar 9.4 rating among adults 18-49. Buena Vista’s “Live With Regis & Kathie Lee” (3.9) looked solid among the morning talkers, while Group W’s new “Vicki!” (1.7) slid a little further for the same week. Talkers featuring Jenny Jones, Joan Rivers and Jerry Springer all posted an unimpressive 1.5 rating.
