TV Links Coast to Coast: First Transcontinental Broadcast
The first live transcontinental television broadcast aired on September 4, 1951, carrying the opening ceremonies of the Japanese Peace Treaty Conference in San Francisco to viewers across the United States. AT&T had just completed a coaxial cable and microwave relay network linking the East and West coasts, making coast-to-coast live television possible for the first time. President Truman addressed the conference via television from Washington, becoming the first president to be seen live simultaneously on both coasts. The broadcast proved that television could unite a continental nation around a single event in real time. Within months, networks shifted from regional to national programming, and television replaced radio as America's dominant mass medium.
