First Official Transcontinental Telephone Call
On January 25, 1915, the first official transcontinental telephone call from New York to San Francisco was made.
Following Alexander Graham Bell’s invention of the telephone in 1876, telephone service spread quickly. By 1890, the Bell telephone had spread to most major cities in the United States. And a year later, the first commercial long distance line extended 45 miles. Phone service between New York City and Chicago began in 1892.
