Answer 4

One of the most important was the spread of radio broadcasting, starting from nothing at all in 1920 to scores and scores of stations by 1925.

I have been fortunate enough to know a few people who were born about 1910, and it was fascinating to hear them describe the enormous impact they felt from listening to these early radio broadcasts, hearing somebody at the very same time as they were speaking thousands of miles away.

When these same people were much older, they saw the arrival of television, and a few of them saw the start of the Internet, but they took it in their stride; it was just more of the same. They still remembered the excitement of of early radio as the time when the world began to shrink.
