Magnetic tape recorders became commercially available in 1948, based on German Magnetophon technology captured after World War II. High-quality audio recording was now accessible to broadcasters and, gradually, to musicians and sound artists. For poets, the tape recorder eventually became a tool for archiving readings and exploring the sonic dimension of verse.

The commercial availability of tape recorders in 1948 revolutionized the way poets recorded and transcribed their performances. This technology allowed for greater accessibility and preservation of spoken word, influencing poets like Allen Ginsberg to experiment with form and delivery.
