Radiotelegraph services sprang up across Europe, North America, and Australia. Marconi’s shortwave “beam” system, launched in 1927, could transmit faster, at lower cost, and with far less power than traditional long-wave systems. Governments took notice, the British Post Office quickly rolled out Beam Wireless services to Canada, Australia, South Africa, and India threatening to disrupt the established cable monopolies.
