TV Ratings: CBS Leads Wednesday Night, 'MasterChef' Climbs on Fox
CBS nabbed a Wednesday win with new episodes of Big Brother (1.9 rating adults 18-49) and Extant (0.8 adults). Both series were steady with last week's showings, though the drama did tick up from its soft premiere.
MasterChef climbed on Fox, rising three-tenths of a point from its last episode to a 1.7 rating in the key demo. Bullseye (0.9 adults) was steady.
Celebrity Wife Swap matched its latest 0.8 rating on ABC.
