The Dragonlance series was the first successful spin off from D&D or what was called at thetime AD&D. Whereas today we have Wizards licensing other properties (Rick and Morty, Critical Role, Stranger Things) and converting them in D&D worlds or sourcebooks, back in the 1980s TSR went the other way with Dragonlance. After the success of the modules, sourcebooks and novels, dozens of which hit the NYT best seller list, TSR created an number of other products under the DL banner.
We saw a Dragonlance boardgame, comic books, animated movie (talk of a live action one never went anywhere), calendars and video games. There was even a Russian musical and songs released by several bands using Dragonlance concepts
