Fast National ratings for Wednesday, July 23, 2014.

"America's Got Talent" and, to a much lesser extent, a series high for "Taxi Brooklyn" helped NBC control Wednesday night in all measures.

Over on CBS, despite a strong week for "Big Brother," "Extant" continued its steady decline.

That was pretty much it for Wednesday's notables, though "So You Think You Can Dance" was very slightly up for FOX, while "Motive" was slightly down for ABC.
