The season finale of AMC's zombie drama "The Walking Dead" lurched all the way to the ratings record book. The episode drew six million viewers, more than any other AMC series.
That let AMC lay claim to the somewhat esoteric but still noteworthy crown of having the most watched drama series in basic cable history among the coveted 18-49 demographic. (An average of 3.5 million viewers in the demo watched the show over the course of the season, and 4.1 million watched the finale.)
Overall, "The Walking Dead" has been by far the most popular series ever on AMC, drawing twice as many viewers as the channel's most critically lauded show, "Mad Men."
