 Also in 1978, TSR Hobbies moved out of Gygax's home and into downtown Lake Geneva, above the Dungeon Hobby Shop.In 1979, the "Dungeon Master's Guide" was published, and radio ads featuring "Morley the Wizard" were broadcast.During this era, there were a number of competitors and unofficial supplements to "D&D" published, arguably in violation of TSR's copyright, which many "D&D" players used alongside the TSR books.
