The Simple Timeline Answer
Telltale's The Walking Dead video game came out first. The game released in April 2012 as an episodic adventure series, while the AMC television show premiered on October 31, 2010. Wait, that's backwards from what most people assume. The TV show actually premiered first. The game launched over two years later. Most folks I talk to at gaming events get this wrong on the spot because Telltale's marketing leaned heavily into the "based on the comic" angle and they didn't do much to clarify the timeline relationship. The TV show hit AMC screens on October 31st, 2010. Telltale Games released Episode One of their title on December 24th, 2012. That's a gap of roughly two years and two months. What made this confusing for a lot of people is that the game's first episode was released during the TV show's third season, which meant a lot of new viewers discovered the game around the same time they were watching the show. The overlap in release windows created this false impression that they launched together or that the game was older. I remember dealing with this exact confusion back in 2013 when I was moderating a forum thread about crossover potential. Someone had screenshotted the game's opening credits, noted the Telltale logo, and asked why the graphics looked more detailed than the TV show at the time. People started arguing for pages about who influenced whom. The actual answer was just a date check. The show had been running for two full seasons and built a massive fanbase before Telltale even announced their project in February 2011.
Here's something most people don't realize though. Telltale didn't make their game as a direct adaptation of the TV show. They based it on Robert Kirkman's original comic series, but they did incorporate some visual design elements from the show's characters. Dave Bautista's Hershel became visually recognizable as Scott Wilson's version. Similarly, the game's Morgan and Duane were clearly inspired by their TV counterparts even though the game's storyline branched away completely after the first episode. This blending of source material is why the confusion persists. People see TV-show-accurate character models and assume the game was built around the show rather than alongside it. Another thing worth noting is the licensing deal. Telltale secured the rights to use the Walking Dead IP through AMC and Skybound, and part of that agreement allowed them to reference show elements. The game's opening narration, the overall tone, the decision to focus on a new original character named Clementine instead of any established show character — those were all deliberate choices to create something that felt connected without being a derivative spin-off. It worked well commercially, which is why there were five seasons of episodes released between 2012 and 2018. The show was still going strong at that point and clearly benefited from the game's presence in keeping the franchise visible to a younger demographic. If you want the exact dates logged somewhere official, the Wikipedia entry for both properties has a clean timeline. But the practical takeaway is straightforward: the TV show premiered first, the game followed, and the overlap in cultural timing is what makes people think otherwise. I've seen this question come up in discussions for over a decade now and it still comes up regularly. The answer hasn't changed since 2012.
