Radioshack

RadioShack Corporation (formerly Tandy Corporation) Established in 1921 in Boston, Massachusetts, by two brothers, Theodore and Milton Deutschmann, who wanted to provide equipment for the cutting-edge field of amateur, or ham, radio. Theodore and Milton Deutschmann opened a one-store retail and mail-order operation in the heart of downtown Boston on Brattle Street, near the site of the Boston Massacre. They chose the name "Radio Shack," which was a term for the small, wooden structure that housed a ship's radio equipment.
