An expanded radio dramatization of the original Star Wars trilogy was produced in 1981, 1983, and 1996. The first two radio series, based on Star Wars and The Empire Strikes Back, were produced and broadcast by National Public Radio as part of NPR Playhouse. A dramatization of Return of the Jedi was produced by HighBridge Audio; it involved most of the same team and was broadcast by NPR's L.A. Theatre Works.
The radio serials were made with the full co-operation of George Lucas, who for one dollar each sold the rights to KUSC-FM, the public radio affiliate at his alma mater, the University of Southern California. The deal allowed the production team full use of the films' sound effects and musical score. Recordings of all three dramatizations were produced by HighBridge, and Del Rey published the three scripts in book form.
Many of the actors involved in the movie were unavailable to reprise their roles: Harrison Ford, for instance, was committed to the first Indiana Jones movie. Two of the actors, Mark Hamill and Anthony Daniels, returned to reprise their roles as Luke Skywalker and C-3PO respectively.

The earliest statements about Star Wars canon, made in 1994 in A Guide to the Star Wars Universe and Star Wars Insider 23, gave a privileged status to the radio dramas and novelizations alongside the films, considering them all to be official benchmarks for what was in the Star Wars universe. In 2000, Lucasfilm reorganized the canon and specified that the highest level, "G-canon," was reserved the films only. Since then, anything in the radio dramas beyond the events of the films has been part of the Expanded Universe, which became Star Wars Legends in 2014.
