Friday TV Ratings 5/19/23: Shark Tank and SWAT Slip for Finales, Fire Country Ends Steady, Blue Bloods Higher on Finale Night (UPDATED)

Ratings Analysis: Though it remains one of Friday's top shows, ABC's 'Shark Tank' (0.35, -0.02) closed out its season on a rather soft note. The unscripted staple declined by two-hundredths from its previous episode and only stayed two ticks above its season low. Following 'Tank', '20/20' (0.19, -0.09) unexpectedly crumbled to a new season low. On CBS, 'SWAT' (0.35, -0.01) shed a hundredth while 'Fire Country' (0.35, 0.00) held steady for its finale. At 10, 'Blue Bloods' (0.34, +0.06) shot up to its highest rating since early April, thus finishing the season in strong fashion. NBC went with a rerun of 'That's My Jam' (0.21) and a 'Dateline' original (0.30, +0.03) that trampled '20/20' head-on. Fox's 'WWE Smackdown' (0.53, -0.03) inched down but easily remained the evening's top program. Over on the CW, 'Whose Line Is It Anyway?' (0.06, 0.00) held even but could only tie the repeat of 'Penn & Teller: Fool Us' (0.06) that led into it. 'The Great American Joke Off' (0.05, +0.01) picked up a precious hundredth at 9:30.
