Telltale CEO Dan Connors indicates that The Walking Dead has sold more than 8.5 million episodes. iOS sales only comprised 25 percent of the total, but it has grown the most compared to previous titles and was more reactive to interest in the TV show.

“It was the culmination of the product, the game of the year awards, the retail push, and it still has a ton of head room in it,” he said. “Apple has featured us a bunch of times for each of the episodes, and it’s in Apple’s Hall of Fame.”

“What we’ve done is have this online buzz going from April to November, and then have this finale to top it off and have that be the biggest event that propels it into the mass market,” Connors added. “It allowed us to capture all that early adopter audience but also gives us the momentum to build a product that can reach out to the mass. Instead of paying a bunch of money to drive a bunch of installs, we have all this momentum and recognition that comes from all the work we’ve done over the five months leading up to the Christmas launch. Then the finale happens, and bam, it’s picked up by a much wider spread.”
