This document discusses the history and elements of radio dramas. Radio dramas were popular in the 1930s-1950s as they relied on narration, dialogue, music and sound effects to tell stories without video. By the late 1930s, radio dramas were widely popular in genres like mysteries and soap operas. After television was introduced, radio drama popularity declined in the US with most being cancelled by 1960. Key elements of radio dramas included narration to set the scene, dialogue between characters, music to transition between scenes or set mood, and sound effects to establish the environment. With podcasting, radio dramas have become popular again as they can be created and distributed easily.
