The original Dungeons & Dragons, now referred to as OD&D, was a small box set of three booklets published in 1974. It was amateurish in production and assumed the player was familiar with wargaming. Nevertheless, it grew rapidly in popularity, first among wargamers and then expanding to a more general audience of college and high school students. Roughly 1,000 copies of the game were sold in the first year followed by 3,000 in 1975, and much more in the following years. This first set went through many printings and was supplemented with several official additions, such as the original Greyhawk and Blackmoor supplements (both 1975), as well as magazine articles in TSR's official publications and many fanzines.
