The Journal of the Travellers' Aid Society
Beginning in 1979, GDW published a quarterly magazine dedicated to the Traveller game system. During its life, JTAS won the Origins Award for Best Role-Playing Magazine and expanded the universe of Traveller. At issue number 25, JTAS transformed into Challenge Magazine and continued to cover Traveller while adding coverage for other role-playing systems. Support for Classic Traveller continued through issue 36.
