The first telephone exchange started operating in Budapest on May 1, 1881. Tivadar Puskás and his brother Ferenc built the equipment. Initially, the phone centre had only 25 subscribers, but its popularity grew steadily. Based on the telephone network and the telephone exchange, Tivadar Puskás's truly great invention, the Telephone Herald (Telefonhírmondó), was born and presented at the Millennium Exhibition.
