radio

{{11}}radio (n.) "wireless transmission with radio waves," 1907, abstracted from earlier combinations such as radiophone (1881) and radio-telegraphy (1898), from radio-, comb. form of RADIATION (Cf. radiation) (q.v.). Use for "radio receiver" is first attested 1913; sense of "sound broadcasting as a medium" is from 1913. WIRELESS (Cf. Wireless) remained more widespread until World War II, when military preference for radio turned the tables.

It is not a dream, but a probability that the radio will demolish blocs, cut the strings of red tape, actuate the voice "back home," dismantle politics and entrench the nation's executive in a position of power unlike that within the grasp of any executive in the world's history.
