Radio broadcasting in the beginning
Radio began as ship-to-ship and ship-to-shore communication. In the early 1900s, several people showed that radio could do more than that. One of them, Dr. Lee De Forest, is widely honored as the father of radio. He made the first public radio broadcast. A fan of opera, De Forest wanted to send the musical entertainment into homes.
His first attempt was on January 13, 1910, from the Metropolitan Opera House in New York City.
However, the broadcast ran into interference from other signals. Only a few listening stations and anyone in the harbor area were able to hear this broadcast. Although there was a lot of room for improvement, it showed what radio could do.

Radio broadcasting today
Fast-forward one century, and the world looks very different. Radio broadcasts are everywhere. Information now travels at the speed of light. Music, news, traffic reports and speeches from world leaders are all on the radio. Can you imagine a world without radio?
