'Walking Dead' Finale Hits Series High

AMC's The Walking Dead hit a series high for its final first season episode Sunday night.

Six million viewers tuned in for the show's sixth episode, including four million adults 18-49. That's up 9% from last week -- which was also a series high.

If you include the show's 11 p.m. encore, the finale delivered a whopping 8.1 million viewers.

All told, Walking Dead has become, according to AMC, the most-watched basic cable series of all time in the young adult demo.

Walking Dead ended with a quasi cliffhanger that felt like a solid finish to the first batch of episodes while still leaving fans ready for more zombie action -- which may not happen until next October, the current target date for the 13-episode second season.
