when the service was not being actively monitored, was used to draw attention to important transmissions. Service was supplied to private homes as well as commercial establishments, including hotels and doctor's offices. At its peak, the service had thousands of subscribers, and many contemporary reviews mentioned that the subscription price was quite reasonable. Initially the Telefon Hírmondó provided a short hourly news program using subscriber's regular phone lines. This was soon expanded into a continuous service, now using the company's own dedicated lines. Its schedule in 1907 was as follows: Radio broadcasting was introduced in Hungary in 1925 with the establishment of Radio Hirmondó, which shared the Telefon Hírmondó studios. With this transition the Telefon Hírmondó became an audio relay system, available for persons who wanted to listen to the radio station without the trouble and expense of purchasing a radio receiver. During World War II the wire network of the company was destroyed, leading to the cessation of the telephone-based service in 1944.

Home subscribers accessed Electrophone programming through their regular telephone lines, by calling an operator for a connection to one of a multiple of program offering. Because this tied-up the subscriber's line, incoming calls could not be received while listening to the Electrophone, although operators were instructed to break-in in case of emergency.
