Defeat and Revivial

Challenge: Radio

In the late 1920s, short-wave radio seemed to make cables obsolete. Radio was cheaper both in equipment and in operations. But it was not always reliable, especially when sunspots flared. And it was not as private. So steps were taken to make sure that the cables survived.

In Britain, the government made telegraph and radio firms merge into a company called Cable & Wireless. In the United States, Congress legislated that a certain percentage of overseas communication would travel by cable.
