ZZTV is a community project started by Dark FLR in 1998. ZZTers can create and contribute channels, which are small ZZT worlds that can contain any kind of content the author wishes: previews of upcoming games, artwork, minigames, stories, etc... These channels are traditionally given names that begin with the "#" symbol (e.g., "#bakedcheese"). All of the channels are sent to the person in charge of ZZTV; the project leader is then responsible for compiling the contributions into a series of volumes and releasing them to the public. ZZTVs are done at the rate of about one per year. Each ZZTV is numbered; for example, the current ZZTV-in-progress is ZZTV11. The person in charge of ZZTV changes fairly frequently; Zenith owned the project between issues 4-7 before passing the mantle on, with the more recent project leaders being MadTom, Commodore, and now bitbot.
