CNN's already-dismal prime time ratings dropped 26% in April compared to the same month last year, according to Forbes. The network's total prime time audience was well under a million viewers at 767,000, while competitors MSNBC and Fox News more than doubled that figure at 1.66 million and 2.395 million viewers respectively.

April ranks as CNN's lowest-rated month among total viewers in nearly four years, since October 2015. CNN's Cuomo Primetime, which has been the network's highest-rated hour, drew a total audience of 917,000 viewers in April, the show's worst-ever performance. Among viewers 25-54, the demographic most coveted by national advertisers, the falloff for CNN was even more stark: down 41 percent. CNN drew 198,000 viewers in the demo, behind MSNBC (255,000) and Fox News (389,000). All three networks saw year-over-year declines in April, with MSNBC down 36% and FNC down 19%. -Forbes
