Dr. Frank Conrad (above), assistant chief engineer of Westinghouse Electric, developed the technology that made KDKA Radio possible. He constructed a transmitter and installed it in a garage near his home in 1916. The station was licensed originally as 8XK with a power of 100 watts.

On Tuesday, November 2, 1920, election night, four men (pictured above) compiled election returns received via wired-telephone from the newsroom at the Pittsburgh
Post newspaper. It is estimated that between 500 and 1000 listeners heard this
broadcast of the world’s first commercial radio station.
