TV Ratings: 'Survivor' Tops Repeat Wednesday, Fox Wins Night With 'Idol'

The two reality series own a night of scarce competition, though each loses a little steam from last week.

Fox scored a nightly win on Wednesday, thanks in part to being the only Big Four network airing all originals. With an average 1.9 rating among adults 18-49, American Idol was off a tenth of a point from the previous week. It averaged 8.4 million viewers, also topping the rest of the pack.

The night's biggest series was Survivor (2.2 adults), down two-tenths of a point from last week. Factoring in CBS encores, the network placed second with a 1.6 in the demo and 7.7 million viewers.

NBC aired only repeats, and ABC's lone original was Mixology. Without an original lead-in, the comedy again pulled a 1.2 rating with adults under 50 -- even with last week. 

The CW saw The 100 (0.6 adults) grow a tenth of a point after a slightly down Arrow (0.7 adults), off a tenth.
