The Walking Dead isn't done delivering huge advertising revenue gains for AMC Networks (AMCX -1.48%), Fool contributor Tim Beyers says in the following video.

Sunday night's season 4 premiere of the zombie drama drew 16.4 million viewers, a new record, on the heels of brisk iTunes season pass sales. Viewers apparently expect series co-creator Robert Kirkman to make good on his promise that season 4 will be "WAY crazier" than prior seasons.

AMC, for its part, is bringing in new cast members to play characters that will be familiar to fans of the comic book. Michael Cudlitz plays former soldier Abraham Ford, Christian Serratos plays Rosita, and Josh McDermitt plays group scientist Dr. Eugene Porter.

Their arrival signals a likely adrenaline push, Tim says, which should keep ratings high while boosting ad rates. After all, last year's ratings boost for The Walking Dead helped AMC grow fiscal 2012 advertising revenue by 16.9%.
