Despite the initial rating for the second episode of "Fear the Walking Dead" dropping significantly from the AMC drama's record-setting premiere, the number of viewers who opted to watch the show later in the week closed that gap significantly.

8.2 million people tuned in to watch the second episode live, while an additional 3.5 million caught up on the show via their DVRs and OnDemand. The total viewership for the episode now stands at 11.7 million, a 46% increase from Sunday's audience, and enough to bring it within 2 million of the series premiere.

The series' debut set a new record with 10.1 million viewers in overnight numbers. After factoring in DVR and OnDemand viewers, the total audience for the zombie series' first episode stands at 13.3 million, 8.5 of which are in the coveted 18-49 age range. That's a 32% and 36% increase over the Live + Same Day ratings reported earlier.

"Fear the Walking Dead," created by franchise creator Robert Kirkman and executive producer Dave Erickson, aims to expand the world of AMC's original "Walking Dead" TV series -- which has been a massive hit since its 2010 debut, and is based on the Image Comics series written by Kirkman and illustrated by Charlie Adlard and, originally, Tony Moore. The first "Fear the Walking Dead" season is set to run for six episodes, and the series has already been renewed for a 15 episode second season.

Starring Kim Dickens, Cliff Curtis and Alycia Debnam-Carey, "Fear the Walking Dead" airs Sunday nights at 9 pm EST on AMC.
