Even before AMC's 'The Walking Dead" has debuted its fifth season, the network has given the zombie drama a guaranteed sixth season.

From an economic standpoint, this makes total sense. The show is the No. 1 show among 18-49 year olds, beating all broadcast networks and averages about 20 million viewers a week, DVR usage included. Even if the show lost some ratings steam this year, it would still be a financial boon for AMC.

On top of that AMC doesn't have a lot of other hits  at the moment. Why not give the producers the comfort and freedom to plan ahead?

The show returns on Sunday with a  bang. (I won't say more since I screened it.)

Afterwards, "Talking Dead" will feature executive producers Scott Gimple and Greg Nicotero plus Conan O'Brien as guests.
