Ways to celebrate

Marconi proved radio could cross an ocean, but it took a Pittsburgh company nearly two decades later to prove people would actually tune in.

Know the broadcast that started American radio

On November 2, 1920, Westinghouse's station KDKA went on air in Pittsburgh as the world's first commercially licensed radio station, with its debut broadcast reporting live returns from the Harding-Cox presidential election.

Meet the engineer who made it happen

KDKA grew out of assistant chief engineer Frank Conrad's amateur ham radio broadcasts of music, talk, and sports scores around Pittsburgh — Westinghouse vice president Harry P. Davis noticed the local following Conrad had built and turned it into a scheduled, licensed commercial station.
