Radio began in 1920 when KDKA produced
their first historic radio broadcast.
Yet, how did they get there?
In 1896, Nikola Tesla first
demonstrated radio waves.
Then Guglielmo Marconi
stumbled upon wires that
could transmit radio waves
over hundreds of yards.
In 1906, Reginald Fessenden was
the first to successfully transmit
a long-distance radio signal.
What did he transmit?
