Direct dial overcomes operator interference
Until 1891, calls were put through by exchange operators, but this was done away with by a Kansas City man who invented the direct dial system because he was paranoid enough to think that the operators were sending his business calls to competitors. He was an undertaker.
In 1927, the first transatlantic call was made over radio waves. During both World Wars, telephone advancements grew by leaps and bounds because of heavy spending by the Defense Department. Innovations resulting from war-time experiments included Bell Telephone’s first mobile telephone system, which connected moving vehicles to landlines via radio. Surprisingly, this was as early as 1946, a year that also saw the development of coaxial cables for major transmission improvements with less interference.
In the 1960’s, telephones were so much a part of the landscape that Bell Telephone could no longer continue to use the alpha-numeric codes for telephone exchanges (remember using numbers like Normandy-7610?) and switched to longer, all numeric numbers. At the same time, transatlantic cables were being laid to accommodate the increased demand for intercontinental telephone communication. One of the most important shifts in telephone history was the launch of the first telephone satellite in July of 1962. TelStar was a joint venture between Bell and NASA and revolutionized telephone communications like nothing that had come before. Satellites in geosynchronous orbit could now be used for long distance calls without the need for laying endless lines of cable and did away with the problem of frequent cable damage and repair.
