The origins of radio
Radio developed as a logical next step from telegraph - the need to find a way to send telegraph signals over of water without cables. But the discovery process goes back much further than that - and features some remarkable leaps of deduction - as well as feats of technological daring.
Wireless comes of age
With the development of wireless, we moved a big step closer to a 'joined up world' - in which every part of Earth was brought within contact.

The technological development that made this possible involved wireless going to sea and taking to the air. The development of radio telephony allowed real conversations over the airwaves - and extended the reach of the telephone.
Radio was the first means of instant mass communication - allowing the possibility to talk to whole populations at once. From the late 1920s on, important events started to become shared experiences for entire nations.

In Britain the technology of broadcasting evolved rapidly so that in just ten years it was accessible to millions of people all over the country.
