The opener of AMC's The Walking Dead averaged 5.3 million viewers Sunday, an original-series network record that more than doubles the typical audience of Mad Men .
AMC has sent out a press release confirming that their new uber-hit zombie TV series, The Walking Dead, will indeed get a second season. The first season will only run six episodes, but the first two episodes have delivered big numbers so far. The debut on Halloween night brought in record-breaking numbers with 3.6 million viewers in the ages 18-49 demographic, and 5.3 million viewers overall. The second episode last night delivered 3.3 million in the 18-49, and 4.7 million viewers overall, making the second season greenlight a very easy decision.
