Wednesday Ratings: Riverdale Grows With 'C-' Series Finale, Superfan Slips Again

In the latest TV show ratings, CBS' Big Brother led Wednesday in the demo, while NBC's America's Got Talent dominated the night in total viewers.

NBC | AGT (with 4.7 million total viewers and a 0.5 demo rating) was down a tick from Tuesday's tallies.

CBS | Big Brother (3.2 mil/0.6) was steady week-to-week, while Superfan (1.2 mil/0.1) slipped to new lows.

FOX | MasterChef (1.9 mil/0.3) was steady.

THE CW | Nancy Drew (380K/0.1) dropped some eyeballs with its series finale (which TVLine readers gave an average grade of "A-"; read post mortem). Riverdale (220K/0.1, read recap) meanwhile ticked up in both measures with its "C-" series finale.

These numbers (Nielsen fast nationals, unless denoted as finals) instead aim to simply illustrate trends or superlatives.
