Nielsen: 9 million viewers for 'Walking Dead'

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.
