The Walking Dead is one of the most popular television shows on cable and it's managed to stay that way through all of the hierarchy changes. When the show was confirmed to be returning for it's fourth season this fall, it was also announced that Season 3 showrunner Glen Mazzara would be leaving the production. THR is now reporting that executive producer Scott Gimple has been promoted to showrunner for the fourth season.

Gimple joined the show at the start of its second season working as a producer and he is credited with writing five episodes. He is also credited with writing the screenplay for Ghost Rider: Spirit of Vengeance among other television series.

The promotion of Gimple makes him the third showrunner for The Walking Dead since its premiere just a few years ago. Frank Darabont brought the series to life and was let go halfway through production on the second season when Glen Mazzara was promoted. Mazzara will part ways with the network when work on the third season has finished.

The Walking Dead returns from hiatus on February 10 and here is a also new TV spot for its return (Thanks to Sean for sending it in!).
