One week after its Bruce Jenner interview dominated the Friday ratings landscape, ABC stayed on top in key demos last night behind “Shark Tank” and the premiere of spinoff series “Beyond the Tank.” CBS, meanwhile, saw nice bounce-back outings by dramas “Hawaii Five-0” and “Blue Bloods.”

According to preliminary national estimates from Nielsen, “Shark Tank” opened things for ABC with a timeslot-winning 1.6 rating/7 share in adults 18-49 and 6.9 million viewers overall, down a bit vs. last week’s timeslot premiere on a night when it was likely boosted by pre-Jenner tune-in. It was followed by the first of three “Beyond the Tank” episodes to air this month, with the premiere scoring a strong 1.5/6 in 18-49 and 6.3 million viewers overall. “Beyond,” which takes a look at how the entrepreneurs featured on the show fared later on with their products, retained nearly all of its demo lead-in from the mothership, and it wouldn’t be surprising to see “Beyond the Tank” matching “Shark Tank” with a 1.6 in the nationals. Closing things out was an unexceptional hour of “20/20” (1.0/4 in 18-49, 4.4 million viewers overall).

CBS had a fairly typical night with its lineup of “The Amazing Race” (1.0/5 in 18-49, 5.5 million viewers overall), “Hawaii Five-0” (1.2/4 in 18-49, 8.5 million viewers overall) and “Blue Bloods” (1.3/5 in 18-49, 11.0 million viewers overall). Both dramas bounced back by multiple tenths vs. last week, with the season finale of “Blue Bloods” ruling the 10 p.m. hour in key demos and standing as the night’s most-watched program overall. Last week’s “Blue Bloods,” which went up against the Jenner interview on ABC’s “20/20,” spiked considerably in Nielsen’s Live+3 ratings, which include three days’ worth of DVR playback. In those numbers, the Tom Selleck drama jumped 83% in adults 18-49 rating —from a 1.02 to 1.86.

NBC ran a distant third last night with “Grimm” (0.9/4 in 18-49, 4.2 million viewers overall) and a two-hour “Dateline” (1.0/4 in 18-49, 5.4 million viewers overall).
