Wonderful interview about the Abbey Road Microphone Collection (UK)
Radio Microphones (under construction)
The use of radio microphones is now widespread across the theatre, film & event industries.
Their wide use is more recent than you may realise, however.
Use on Films:
Peter Handford, the sound recordist on Murder on the Orient Express (1974), shot at Elstree Studios, ‘pioneered the use of concealed radio microphones for feature film production’ (hidden in the furniture in the train carriages).
Use in Theatre:
Became widespread in the 1980s due to the new technologically-advanced musicals where sound reinforcement was needed to beat the volume of the electronic instruments and rock instruments in the band.
Use in Live Music Performance:
EDC (based in the UK) had a range of hand-held radio microphones available in 1979.
