‘The Walking Dead’ Hits TV History But Falls From 2016 Finale In
Live+3

by Dominic Patten

The not-so-good news is that the Season 7 finale had a zombie-sized
ratings bite taken out of it in viewership and the demo for its Live+3
results. Coming off a very competitive night Sunday, The Walking Dead
drew 15.5 million total viewers and 9.7 million in adults 18-49, for a
7.6 rating in the time-shifted viewing metric, down 15% and 16%,
respectively from the L+3 results of the Season 6 ender of last year —
itself down 10% and 15% from the record-breaking Season 5 finale in
2015.

The good news for AMC is that the series based on Robert Kirkman’s
comics has truly planted a flag in small-screen history. It remains
the highest-rated show on TV despite the declines this season, and now
holds the title as the only drama to hold the top spot in adults 18-49
for five years in a row.
