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干涉 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?
