Back in the race after 3 weeks off the air, an original Shark Tank (1.5/5) last night saw pitches from beekeepers and personalized plush toy makers as well as the duo from Focus Athletics trying to induce Mark Cuban and gang to invest in their lightweight runners. Down 17% among adults 18-49 from its last original, the entrepreneurial reality series was the top rated show of the night. Shark Tank also took a bite out of its 9 PM time slot by 36% over Hawaii Five-O (1.1/4) and the 2-hour Dateline (1.1/4), which were down 8% and 15% respectively from last week.

All of which helped ABC take the key demo on Friday with a 1.3/5 rating. The network’s night started with comedies Last Man Standing (1.2/5) and Cristela (1.0/4) even with 139049_MG_7841their April 3 shows. But the real kicker was the kicker of 20/20 (1.4/5) at the end of the night at 10 PM. Proving that the get has still got it, Barbara Walters’ interview with former teacher and former convict Mary Kay Letourneau Fualaau and her former 6th Grade student lover and now decade long husband Vili Fualaau was a big winner on Friday night. A winner that saw the news mag rocket up 75% in the demo from the week before. Add to that the fact that Walters’ sit-down with the Fualaaus delivered  an audience of 5.98 million for a 62% surge in viewership over  20/20’s Good Friday show and you have all the proof you need that the ex-View co-host still goes large. Those are 7-week demo and audience high results for 20/20. A ratings reality that also sets the Olympic bar for Diane Sawyer’s sit-down with Bruce Jenner on April 24.

As ABC took the demo top spot, CBS was No. #1 in viewers with 8.20 million last night. With hefty audience numbers for all its offerings on Friday, the big boy for CBS was once again Blue Bloods (1.2/4), with 10.13 million tuning in. The 10 PM NYPD family drama saw quite the tire iron throw from Donny Wahlberg on Friday night as it also saw a dip of 7% in the demo from last week. CBS’ Friday started with The Amazing Race (1.1/4), which was down 15% from its Good Friday airing.

NBC’s only dramatic offering of the night was 8 PM’s Grimm (1.1/4), which bopped up 10% from its series low 18-49 result of April 3. Fox showed the 2010 flick Date Night starring Tina Fey and Steve Carell. The movie generated a 0.6/2 rating for them.
