 Due to the expense of recorders and the limitations of the recording media, home recording of broadcasts was not common during this period and it was usually limited to brief excerpts.The lack of suitable home recording equipment was somewhat relieved in 1947 with the availability of magnetic wire recorders for domestic use.These were capable of recording an hour-long broadcast on a single small spool of wire, and if a high-quality radio's audio output was recorded directly, rather than by holding a microphone up to its speaker, the recorded sound quality was very good.
