Trivia: Land of Oz
- Torch the Franchise and Run: L. Frank Baum attempted to do this when he grew tired of writing sequels despite the demand from his fans and publishers. He had established that nothing dies in the land of Oz, so he couldn't kill anyone off. In the sixth book, he tried to use the Literary Agent Hypothesis to justify never writing a single thing about Oz again because an invasion caused Oz to become isolationist and totally cut off all contact with the outside world, thus promising to never ever write another story about Oz ever again. When his other books failed to sell as well, he had to begin writing stories about Oz again to pay his bills, backpedaling and explaining that they discovered the radio in Oz that Dorothy could use to broadcast Baum news about Oz.
- Outlived Its Creator: When Baum died, the publisher found another author to continue the books.
