London Times, June 17, 1925, page 18:
LICENCE WITHDRAWN BY POSTMASTER-GENERAL.
The Electrophone, Ltd., the company which for many years has run the electrophone service last night issued the following notice to subscribers:--
"In consequence of a large number of our
subscribers having given up the electrophone in favour of wireless, the revenue has so largely decreased that the Postmaster-General has decided to withdraw the licence granted to this company, and has served notice that the electrophone service is to be terminated on the 30th inst. We have, therefore, no option but to hereby notify you with extreme regret that after the 30th of this month we shall no longer be in a position to continue the electrophone hearings."
