DGP got its start with The Traveller's Digest and was the Traveller licensee of the late 1980s and early 1990s.

Not only did they do many high quality publications on their own, but they also produced some of GDW's best work of the period, and notably also produced the Megatraveller revision.

DGP shut down following GDW's decision to take Traveller: The New Era in house, and afterward all of their IP was bought by a "fan" who has since sat on it, asking astronomical fees for its use.
