NEW YORK (AP) — Television viewers can't get enough of those zombies.

The Nielsen ratings company said Monday that 9 million people watched the season finale of "Walking Dead" on AMC Sunday night. That's the largest audience ever for an episode of the series, which is in its second season.

It was the most-watched original drama episode ever on basic cable among some key demographics, including viewers under age 49 and among young men, although it fell short of being the most-watched drama ever on basic cable.

The show's season average of 6.9 million viewers was up 32 percent from the first season.
