TV Ratings: Fox's 'Cosmos' Pulls 8.5 Million Viewers Across 10 Networks

The simulcast, which saw its best performance on the broadcast network, kicks off its 13-week run without a gargantuan haul.

Sunday's incredibly crowded TV schedule saw Fox pitting science against scripted heavy-hitters like The Walking Dead, True Detective and ABC's impressive launch for Resurrection.

The broadcast net's follow-up to Carl Sagan's 30-year-old Cosmos: A Personal Voyage brought in 8.5 million viewers across 10 networks -- including Fox's cable nets and the National Geographic Channel. It's a modest haul, given the scope of the launch, but Fox cited global projections north of 40 million viewers for the first week.

Among adults 18-49, Cosmos grossed a 2.9 rating.

Cosmos: A Spacetime Odyssey, produced by Seth MacFarlane and hosted by Neil deGrasse Tyson, fared best on Fox. Fast National returns have the network earning a vast majority of the total haul with 5.8 million viewers.

As is the case with all non-live TV, expect a great deal of attention on how much of a lift Cosmos gets from time-shifters.
