Before the invention of radio, people were extremely limited in their ability to communicate over great distances. The telegraph was the most effective way to instantly transmit a message from one point to another, but was limited by the necessity of telegraph wires connecting the points of origin and destination.
Radio, on the other hand, uses electromagnetic waves that propagate through the air, requiring only a method of broadcasting and receiving the signal. Today, millions and billlions of messages are sent wirelessly on a daily basis. From their sender, they may reach as far as outer space before being bounced around a network of satellites, where they are then directed to their destination anywhere on the planet.
Interestingly, radio waves, like other electromagnetic waves, propagate from their point of origin in a spherical bubble, and will travel indefinitely until their path is interrupted. This means that the first radio signals ever sent are still traveling through space as we speak.
When radio sets were first invented, they were considered a luxury, but in modern times, nearly every automobile produced comes equipped with a radio. For this reason, anybody capable of transmitting a message over radio waves is immediately able to reach a fairly wide audience, making it an effective form of advertising to anyone willing to pay for the airtime.
