The first automated telephone switching system was developed by Almon Strowger, an undertaker in Kansas City, Missouri. According to lore, an operator was directing calls to her husband, a competing undertaker. The system was first used in La Porte, Indiana, in 1892. In 1910, only 300,000 had automated service (dial rather than operator interaction) out of 11 million subscribers. Automated systems reduce labor costs and ensure privacy to the customer. The first fully automated office started business on December 10, 1921.
