TV Ratings: March Madness Ends on a Low Note for NCAA and Turner

The Turner suite of channels led Monday night with its coverage of NCAA Championship basketball — but the big game is pacing for an all-time low.

TBS', TNT's and Tru's shared coverage of Villanova's decisive win over the University of Michigan sunk 29 percent from the comparable 2017 game with an all-time low overnight 10.3 rating among households. That capped off a particularly modest run for March Madness.

Adjustments give the game an average 16.5 million viewers, likely a biproduct of the blow-out score — the most lopsided for a NCAA Championship in over two decades. Compared to CBS coverage in 2018, the game was down an unfortunate 28 percent. 

It was still the biggest thing on TV on Monday night, no doubt contributing to the season low for ABC's American Idol. The singing show was down to a 1.4 rating among adults 18-49 and 7.1 million viewers, losing to The Voice by a solid half-point in the key demo. The Voice led broadcast with a 1.9 rating in the demo and 9.9 million viewers.

CBS and Fox both took a pass on airing originals against basketball, but NBC and ABC both put out original dramas at 10 o'clock. The latest episode of NBC's Good Girls held a 0.9 rating in the key demo, while ABC newcomer The Crossing had a slow start with a 1.0 rating among adults 18-49 and 5.5 million viewers. It did win the hour, at least on the Big Four.
