In 1927, folks in the Fresno, California area went down to the local cinema to learn how to use those new-fangled dial telephones that everybody was talking about. This is the charming footage, a combo of live action and cartoons, created by the American Telephone and Telegraph Co. (AT&T) that they saw 91 years ago.
In 1922, New York City was introduced to dial. The first popularized dial telephone was a desk set candlestick model; the smaller, more familiar desk set came later.
It took decades for dial to sweep the entire Bell System. The last holdout was Catalina Island, off the coast of California, which finally converted to dial in 1978. In Camp Shohola, Pennsylvania, an internal automatic switch system still connects campers with the outside world, it's the oldest functioning Strowger switch in the world.
