TSR was the game company that created Dungeons and Dragons role-playing game. They also published several licensed games (Indiana Jones, Buck Rogers) and other unique games with different themes (Gamma World, Boot Hill, Star Frontiers).

TSR dominated the RPG industry for the first twenty years of its existence.

Wizards of the Coast acquired TSR in 1997, and later allowed the trademark to expire.


In 1994, TSR sent out Cease and Desist notices to several ftp sites with gaming (RPG) materials, insisting that any of their materials be removed, and later announced that D&D-related content could only be hosted at single company-approved site.

Recently, TSR, Inc. issued a policy statement regarding the unlicensed use of TSR owned trademarks and copyrights in several creative efforts published on the Internet. TSR’s policy remains unchanged regarding these infringements. We generally ask that you do not publish materials which incorporate our trademarks and copyrights. However, we believe we have a working solution for gamers who wish to exchange via the Internet any gaming material they have created.

TSR is pleased to announce a licensed Internet FTP file server. MPGNet’s site (ftp to ftp.mpgn.com) will carry a license that allows your creations to be shared with the world via the Internet. In order to distribute your texts, software and message digests via this server, you must include the following disclaimer:

The item is made available by MPGNet under license from TSR, but is not authorized or endorsed by TSR. The item is for personal use only and may not be published or distributed except through MPGNet or SR.[2]

The end result: online D&D activity came to a halt just as the internet started to get really active, and other games rushed in to fill the void. The resulting boycott is rumoured to have hit TSR harder than they were willing to admit.[3] and may have The crackdown is remembered as one of the early intellectual-property scuffles in online fandom and is referred to in the article Fan Fiction on the Line.
