Once upon a time radio was the principle medium for home entertainment. Radio drama, as it was known, provided hours of enjoyment for millions of listeners. It even sometimes frightened listeners as did Orson Wells' Halloween radio production of War of The Worlds in 1938.

Radio has, for the most part, abandon the art form that it had nurutred for years through the sound artistry of producers such as Orson Wells and Norman Corwin.

When radio became an all-news, all talk, or all music medium, audio artists turned to tape, disc, and now the Internet for distributing their creative work.

Audio theater is very much alive with writers and producers generating all new dramatic presentations across the country. It is a medium that combines voice acting, sound effects and music to present a dramatic audio performance.

Audio art in Europe has grown over the years. In Germany and elsewhere it is known as "horspiel" which is pronounced as "her-speel," that can be best translated as "ear-play". Horspiel has evolved into a sound art that explores the expressive forms language can take.
