[5] The show presents the history and downfall of theme parks and attractions from around the world, most notably those of Disney, Universal, and Six Flags.

[10][11] Initially, the Defunctland YouTube series was meant to be a showcase for attractions that would be a part of a virtual theme park of the same name.

Soon after starting the channel in 2017, Perjurer uploaded a video titled "Defunctland VR: The Sorcerer's Hat" to show off the initial prototype of the park.

About a year later, Perjurer made a post on his website about the VR Park to explain that it was still happening, as well as show off some of the progress up to that point.

A video was uploaded in January 2021, showing a virtual reality version of 20,000 Leagues Under the Sea: Submarine Voyage, as well as other parts of the park.

The first season of Defunctland, created by Kevin Perjurer, premiered on the YouTube channel of the same name on February 15, 2017, and lasted for 22 episodes.

The initial run of the series, hosted by Randall on the Defunctland YouTube channel, lasted for only two episodes in April 2018.

The series was rebooted with a third episode on the Themed Alternative YouTube channel, hosted by the mysterious "K", voiced by Bleaker, written by Corvyn Hartwick and edited by Heath Jinkins.
