The first radio broadcast was aired in 1920 from the English offices of Guglielmo Marconi in 1920. This transmission was the birth of modern radio and eventually became the basis for the formation of the British Broadcasting Company, or the BBC.

Digital radio is now available in most advanced countries, offering a high quality and secure alternative to analog sources. Radio is not only used for entertainment purposes, but is also a key part of many technologies.

Radio waves allow for the remote control of consumer gadgets like model aircraft and cars. The same technology is employed by the military to control unmanned vehicles, on land, in the air and in the water. Medical technology has been one of the great beneficiaries of radio technology, with X-rays being used daily across the globe to improve medical diagnosis.

Other products that you can find around the home which use radio waves are microwave ovens, cell phones and television sets.
