You won't believe these 10 facts about people. A dial tone is the signal that a person hears on a landline telephone before he dials a phone number. In most instances, the signal disappears once the first number is dialed. In most cases, cell phones do not have a dial tone.
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. However, speed dial did not become common until the 1980s when touch tone phones had become commonplace.
