Thursday TV Ratings 2/18/21: Law & Order: SVU Steady After Break, Mom Slips After Cancellation, Clarice and The Hustler Also Tick Down (UPDATED)

Preliminary Analysis: A week after their triumphant return, CBS was down across the board with 'Young Sheldon' (0.8), 'B Positive' (0.6), recently-canceled 'Mom' (0.6), 'The Unicorn' (0.4), and 10pm drama 'Clarice' (0.4). 'Unicorn' shed two-tenths while all the other programs were down a tenth. On ABC, 'The Hustler' (0.4) inched down while 'Celebrity Wheel of Fortune' (0.8) and 'The Chase' (0.6) were flat. On NBC, 'Law & Order: SVU' (0.7) held even after a month-long break and led into the first installment of 'Dateline' multi-part crime drama 'The Widower' (0.5). The latter was a good bit above the 0.34 that 'Dateline' itself posted a week ago. Earlier in the night, 'Mr. Mayor' posted its third-straight 0.5 rating and was followed by a 'Young Rock' encore (0.3). Fox was steady all-around with 'Hell's Kitchen' (0.7), 'Call Me Kat' (0.5), and 'Last Man Standing' (0.4). The CW's 'Walker' (0.2) matched its previous episode but 'Legacies' (0.1) lost a tick.

Finals Update: Celebrity Wheel of Fortune (+0.1), The Hustler (+0.1), Mom (+0.1) and The Unicorn (+0.1) adjusted up.
