The Walking Dead Season 3 finale was watched by 12.4 million viewers last night on AMC. That and the 8.1 million the zombie drama drew in the adults 18-49 demographic were highs for the series. Written by now-departed showrunner Glen Mazzara, the finale on Sunday was up from the 9 million viewers who watched the show’s Season 2 finale last March. The series’ viewership last night and 18-49 result topped both the night and the week in total viewers and the demo. The Walking Dead pulled in 10.2 million viewers for its midseason finale December 2 last year. The record-breaking series garnered 12.3 million viewers for its February 11 Season 3 winter return, with 6.8 million in the 18-49 demo. Those numbers had been series highs.
The Walking Dead’s Season 3 average in adults 18-49 is beating everything else on TV this season, including heavyweights like The Big Bang Theory, American Idol, The Voice and Modern Family. The series was renewed for a fourth season late last year, with the new season expected to begin airing on AMC in October, according to series executive producer Gale Anne Hurd.
