The zombie drama, based on the graphic novels created by Robert Kirkman, drew 9 million total viewers, including 6 million in the advertiser-coveted adults 18-49 demo, 5.3 million in adults 25-54 and 3.2 million in 18-34; the demo numbers topped basic-cable records set by February's Season 2 midseason premiere. That episode, which followed the show's two-month hiatus, drew 8.1 million total viewers, 5.4 million in 18-49 and 4.4 million in 25-54.

The episode was up more than 50 percent in total viewers compared with its Season 1 finale. Including repeats at 11:30 p.m., the installment drew 10.5 million total viewers.

The February numbers topped another mark set by October's 90-minute Season 2 premiere. That episode, which followed a nearly one-year wait after the six-episode freshman season of the drama starring Andrew Lincoln, marked a then-record for any drama in basic-cable history in the demos; it drew 4.8 million in 18-49 and 4.2 million in 25-54, shattering nearly 10-year-old marks in the demos.

In Sunday's episode, the survivors learned the results of the Season 1 cliffhanger: what Jenner (Noah Emmerich) whispered to Rick (Lincoln) at the CDC before its dramatic explosion. In addition, the final moments introduced the location of the third season -- the highly anticipated prison featured in the comics -- as well as the introduction of the iconic heroine, Michonne (Danai Gurira), featured in the series.

Sunday's finale was up drastically over the "monumental" penultimate episode, which featured the heavily hyped (and somewhat anticipated) departure of Shane (Jon Bernthal). It drew 6.9 million total viewers and 4.6 million in 18-49, with 4.1 million in the 25-54 metric.

Sunday's record ratings come as Kirkman faces a lawsuit from childhood friend Tony Moore over financial compensation to the lucrative franchise.
