Zombies, red-nosed reindeers and veteran TV news reporters had a memorable week in the TV ratings.

AMC's season finale of "The Walking Dead," the TV version of a comic-book zombie series, scored the biggest audience ever for a basic cable drama series in the key young demographic of viewers 18 to 49, the Nielsen Co. said Tuesday. Six million people overall watched the final episode in its first airing Sunday night. Add in two later repeats that night, and the total audience climbed to 8.1 million viewers.

CBS' traditional airing of "Rudolph the Red-Nosed Reindeer" scored 12.2 million viewers last week, beating out all other holiday fare.

Lesley Stahl's "60 Minutes" interview with Facebook leader Mark Zuckerberg vaulted that show into the top five of the week's most popular shows. The "60 Minutes" online post-show special, revealing a redesign of the site, reached the biggest audience that feature has ever achieved, CBS said.

Less impressive for CBS was Wednesday's Grammy nominations concert. While essentially an hourlong promo for the awards themselves, it was a costly one, with only 5 million viewers tuning in. It was the third year of the nominations special, and the least-watched, Nielsen said.
