Theater of the Mind. In the "golden days of radio", radio dramas created a theatrical experience that seemed extremely real to listeners. Orson Wells' 1938 Halloween eve production of H.G. Wells "War of the Worlds" caused widespread panic, since people actually believed that the Martians were invading.
Radio dramas were heightened, not only by good acting, but also by the show's sound effects crews that made the program coming over the airwave seem like it was actually happening. They were creating these effects live, just as Jack Foley and others did on some the earliest movies with sound.
They would use props like windows, doors, weapons that fired blanks, and whatever they could physically drop, shake, hit, slide, or move to create a soundscape that caused the radio listener to suspend all disbelief.
Because radio produced such rich convincing images using only sound, it was called "theater of the mind". Even today on television and in movies the sound effects track adds the realism that make the prop weapons, vehicles, and the actions of the actors seem very real and often even larger than life.
