A jazz musician named Teri Pall invented a version of the cordless phone in 1965 but could not market her invention, as its 2-mile (3.2 km) range caused its radio signals to interfere with aircraft communications. In 1968, she sold her rights to the cordless phone to a manufacturer who modified it for practical use.
History of the Smartphone. Alexander Graham Bell is the inventor of the telephone. In 1878 he made the first phone call. Telephones have not only come a long way, but may one day be completely obsolete. Motorola introduced some of the first cellphones to the public during the 1980s. These cellphones were completely unlike the cell phones of today since they were not at all compact nor by any means cost effective. Some of these cellphones cost as much as $4,000, and weighed over 2 pounds! The first smartphone was developed by IBM and BellSouth, which came out to the public in 1993.
