Radio art treats broadcasting itself as an artistic medium. It began in the 1920s, when German producers probed what the new apparatus could do: Hans Flesch's play Zauberei auf dem Sender (1924) tested the dramatic possibilities of live transmission, and Walter Ruttmann's Weekend (1930) built an acoustic montage entirely from recorded city sound. In the 1940s Pierre Schaeffer's experiments with recorded sound fed into musique concrète and turned the broadcast studio into a compositional space. Dedicated platforms gave the form a home from the mid-1980s: Kunstradio - Radiokunst on Austria's Ö1 (1987) and New American Radio in the United States (1987-1998). Later projects pushed radio art onto the internet and across networks of distant locations. What unites the field is attention to the relationship between artist, transmission technology and listener.

Defining characteristics
Sound collage and montage: field recordings, speech, music and noise cut into acoustic compositions
The transmission itself as material - static, interference, tuning and signal loss left audible
Voice and sound poetry treated as sculptural texture rather than plain speech
Paced for listening without images, using silence and real broadcast time structurally
Live and networked pieces that connect distant locations through simultaneous transmission
Documentary material, interviews and audience participation folded into the artwork
