A "choose your own adventure" television. I might be dating myself (or just admitting more than I should), but as a kid I used to read a lot of those "choose your own adventure" books. You know, the ones where a junior adventurer goes looking for Mayan treasure, and, at the end of each page, the reader must choose which subsequent page to turn to and thus which path the story will take. Sometimes, you'd end up dead; other times, you'd strike it rich. The books were a literary video game. It was pretty much the only thing my parents could get me to read (hence the lack of Hemingway influence in my writing).
