Winter is coming...again.
Coming off a record-breaking premiere, HBO has announced that "Game of Thrones" has been renewed for a fourth season.
Sunday's season-three opener broke series ratings records with 4.4 million viewers tuning in, up four percent from the season-two finale.
It was also a good day for fantasy television shows. 12.4 million people watched the season-three finale of "The Walking Dead," which was the largest audience in the series history.
Lesson learned: zombies and Westeros are so hot right now.
