Friday TV Ratings 8/20/21: Greatest #AtHome Videos Returns with a New Low, WWE SmackDown Stays on Top, Dynasty Slips (UPDATED)

Preliminary Analysis: To the surprise of no one, Fox's 'WWE Smackdown' (0.6) was the evening's highest-rated program. The wrestling-competition program held steady with its previous telecast. On CBS, the premiere of 'The Greatest #AtHome Videos' (0.3) went a tenth below the last time it was on the air back in July 2020. 'Secret Celebrity Renovation' (0.3) held even in the 8pm slot while a repeat of 'Blue Bloods' (0.2) posted a modest rating at 10. ABC's rerun duo of 'Shark Tank' (0.4) and '20/20' (0.3) outpaced NBC's 'American Ninja Warrior' (0.3) and 'Dateline' (0.3) encores. The CW had a flat 'Burden of Truth' (0.1), but 'Dynasty' (0.0) dropped back down into irrelevancy.

Finals Update: Repeats of American Ninja Warrior (-0.1) and Dateline NBC (-0.1) adjusted down.
