1881 E. J. P. Mercadier Brit. Patent 3929 (1882) 1 My Invention relates to a system of multiplex and self-revertible ‘teleradiophone’. By the word ‘teleradiophone’ I mean a system of electric telegraph, in which the signals are produced by radiophonic effects.
1967 Critic (Chicago) Aug. 62/3 Professor McLuhan's statement..that ‘the extension of one sense tends to throw the other senses out of phase for a time—the extension of the eye by the tele-micro-scope, for instance, or the speed of personal communication by tele-radio-phone’.
2000 Amer. Heritage Invention & Technol. Summer 31/2 Mercadier suggested that the teleradiophone, or simply radiophone, might be a more appropriate name for the device, and many in the scientific community adopted the latter term.
