Techopedia Explains Speed Dial
Speed dial was introduced in the early 1960s, and was displayed at the Bell Systems Pavilion at the 1962 World’s Fair. This system used punch cards to store the phone numbers, and when someone wished to dial a particular number, the corresponding punch card was fed through a slot on the phone and dialed automatically.
