50th Anniversary of Regular Radio Broadcasting 21.11.1973

The stamp on this cover and the cover itself were issued to commemorate the 50th Anniversary of Regular Radio Broadcasting in Australia.
Radio is a way of transmitting signals without wires. It uses electromagnetic radiation to transmit sounds made in one place to listeners in many places. Radio is also known as 'wireless telegraphy', or 'wireless', as earlier methods for sending signals (such as the telegraph and telephone) used wires. Australia adopted radio for communications at sea and in lighthouses, and wireless telegraphy gradually replaced the Overland telegraph which had been completed in 1872.
From the first public radio broadcast in 1923, public and domestic radio sets encouraged communities of listeners. Families and groups gathered around a wireless box or radiogram. Then as radios became cheaper and more portable – particularly with the introduction of transistor radios from the 1950s – personal radios became common, and individuals could listen according to their own preferences.
In December 1922, the Australian Government issued “The Regulations: radio laws for the amateur”. The first licensed broadcast station in Australia, under these new regulations, was 2CM, owned by Charles MacLurcan. The licence (number one) was signed by the Prime Minister, The Rt Hon Billy Hughes. Callsign 2CM is listed by the Federal Government as Never to be Reissued”, in recognition of the pioneering achievements of Charles MacLurcan. 2CM was the first radio station in Australia to publish a regular program guide.

Thank you Maria.
