While The Walking Dead and Invincible feel like they have been around forever, the truth is they haven't. The Walking Dead began in 2003 as a comic book series; it would later be adapted into video games, TV shows, and much, much more. Invincible also began in 2003, but its animated series adaptation on Amazon Prime didn't come along until 2021. Behind both is Skybound Entertainment, the company responsible for each IP's growth into different vectors outside the comic book space.
