Despite a high-profile speech by the President, RNC coverage was down on CBS, hitting a 0.2 and tying Monday and Tuesday's RNC results (both of those nights had Love Island as a lead-in, so perhaps there's a theme there). Big Brother kicked off the night for CBS, down a tenth to 1.0, in-line with most of its results this season. The first post-BB episode of Love Island was up a tenth to a 0.4, tying the premiere.
ABC had more repeats of Holey Moley and To Tell The Truth. The TTTT encore was down from last week to a 0.4, and Holey Moley was steady at 0.4. Speaking of 0.4s, that's how their Republican Convention coverage rated, up a notch from Wednesday's 0.3 and in-line with last week's DNC coverage which featured Joe Biden's speech.
NBC kicked their night off with a repeat of The Wall at 0.4, followed by a Law & Order: SVU encore at 0.3. Republican Convention coverage was also at 0.3, steady both with Wednesday's RNC rating and last Thursday's DNC rating.
Fox had two hours of MasterChef again, but nobody really cared with a 0.2 and weak enough ratings to put Fox in dead-last in the viewer race for the night.
The CW had another unusually-strong Mysteries Decoded encore at 8, followed by a Penn & Teller: Fool Us encore at the typical CW 0.1.
Finals Update: Republican National Convention coverage on NBC (+0.1) and CBS (+0.1) adjusted up. Mysteries Decoded (-0.1) adjusted down.
