## Letters to the Editor

Letters to the Editor:
"I wish to utter an emphatic protest against the action of the Radio Department in granting 5WH a broadcast licence. They swamp most other stations on the dial". Letter to the Editor, 27 Sep 1932.
"Radio is the theatre of the mind; television is the theatre of the mindless". Anonymous.
"One might purchase a receiving set, but what if there is nothing to listen to, or if the transmitter is put to such poor use as to make the invention next to worthless, except as a scientific curiosity?" Adelaide Advertiser Editorial 24 Nov 1924, titled "The Broadcasting Problem – 5CL".
"I am nauseated by the obviously artificial, affected diction of some radio announcers. One is almost led to believe that such manner of speech is an essential requirement for the job". Letter to the Editor, 24 Oct 1940.
"The A.B.C. apparently considers what is good for the listener, and not what he wants. Nothing has been done for brass bands, but thousands have been spent on symphony orchestras and other entertainments for the educated only. Some thought should be given to entertaining the masses?". Letter to the Editor, 23 Mar 1937.
