NEW YORK - In an illustration of how the television world is changing, the hottest drama this fall is on cable.
AMC's creepy "The Walking Dead" pulled in 9.5 million viewers for the second episode of its third season on Sunday, a week after nearly 11 million watched the season premiere. AMC aired the episode two other times later Sunday, and the Nielsen ratings company said a total of 14 million people watched at least one of them.
The most-watched drama on broadcast TV last week, CBS' "Person of Interest," had just under 14 million viewers. The two "NCIS" dramas on CBS' Tuesday lineup are usually more popular but were pre-empted for the presidential debate last week.
"The Walking Dead," about a sheriff's deputy fighting zombie-like people, is even more impressive among the 18-to-49-year-old demographic, the sweet spot for most television advertisers.
