Primetime Cable Ratings: April 21, 2015

NBA Playoffs dominated the tuesday night cable ratings, averaging over 3.5 million viewers and a 1.6 rating in Adults 18-49, for over five hours of coverage, on TNT. The late game drew an impressive 1.7 demo rating, topping everything on Network TV, except THE VOICE.

DEADLIEST CATCH cooled off a bit, dropping a half million viewers and 25% in the demo, from last week's season premiere. But, the 10 p.m. companion show held onto 2.3 million of those viewers for another hour.

IF LOVING YOU IS WRONG was the top scripted original series, with 2.2 million viewers. It remained flat, week-to-week.
