From TWD website: We are very happy that we can now announce that AMC has officially picked up The Walking Dead for an eighth season! With the news coming on the heels of the Season 7 Premiere AMC president Charlie Collier released this statement:
“Eeny, meeny, miny, more. What a joy to partner with Robert Kirkman, Scott M. Gimple and some of the hardest-working people in television to bring The Walking Dead to the fans. And, most important, thanks to those fans for breathing life into this remarkable series right along with us.”
