Grammys? What Grammys? Airing against the second most watched Grammy Awards in history, AMC’s mid-season premiere of The Walking Dead at 9 PM posted rating records of its own. The zombie drama hit series highs in all categories with remarkable 8.1 million total viewers, 5.4 million adults 18-49 and 4.4 million adults 25-54. The Walking Dead‘s 18-49 and 25-54 deliveries were the highest ever for a basic cable drama series, beating the previous record, posted by the AMC zombie series’ Season 2 opener in October by 12% and 6% respectively. In total viewers, The Walking Dead‘s midseason debut ranks behind only the series finale of USA’s Monk and 4 episodes of TNT’s juggernaut The Closer. For the night, The Walking Dead averaged 10.1 million viewers, including the 11 PM and 12:30 AM encores. At 10PM, the premiere of Kevin Smith’s unscripted series Comic Book Men held onto a quarter of its huge lead-in, drawing 2 million total viewers. “It is a great night for AMC,” the network’s president Charlie Collier said. “We’re thrilled to see this incredible record breaking response to The Walking Dead, and Comic Book Men is off to a strong start as well.”
