The AMC has reportedly quoted that the very successful TV series The Walking Dead would be renewed for a fourth season which will be aired from February 2013. The unexpected news, however, is that the series show runner Glen Mazzara would be parting ways with the channel. Due to a high difference of opinion, it was decided that he should step down from the show. The show which will be revived from next year will move the track forward with the protagonists taking refuge in a world after the apocalypse has struck. New characters would also be introduced. So, keep watching.
