Bring out your Dead!

The Walking Dead is a ratings behemoth — especially for cable, and especially in Season 4. There is no bigger show in the 18-49 age group. So it’s no surprise to see TWD on the list of Yahoo’s most-searched TV shows for 2013. It is kind of a surprise that it doesn’t top the list.

Here are the top 10 most-searched TV shows on Yahoo for 2013:

1. American Idol

2. Dancing With the Stars

3. Duck Dynasty

4. The Walking Dead

5. Young and the Restless

6. Game of Thrones

7. South Park

8. Breaking Bad

9. Big Bang Theory

10. The Voice

At least Yahoo users still love Idol, even if its ratings are slipping. Duck Dynasty was already doing well before the recent Phil Robertson controversy, but that probably only helped it in the search rankings. Dancing With the Stars airs two full seasons a year, and even though its own ratings have also slipped it was still the most-watched reality TV show of 2013.

You get a different story if you check out Google Trends' charts. Their top 10 most searched TV shows were Breaking Bad, then Duck Dynasty, The Big Bang Theory, Good Morning America, South Park, True Blood, Big Brother 15, New Girl, Castle and Scandal.

No Walking Dead. Why is that, do you think? Do TWD fans already know what they want without having to resort to search engines? Are we that self-sufficient, or is there something else at work?

It’s really cool if you look specifically at Google’s data for The Walking Dead. Under the U.S. regional interest map, it looks like West Virginia has the highest search volume index. In terms of cities, San Diego is at the top for TWD search. Some of the top "rising" search terms included "andrea walking dead," "daryl walking dead," "norman reedus," "glenn walking dead," "walking dead merle," and "the governor."

Very interesting stats. Check ‘em out.

What search terms do you tend to use, when you look for Walking Dead info? Do you use Google, Yahoo, other?

The Walking Dead Season 4 returns on Sunday, February 9 at 9 p.m. ET on AMC.
