Dial phones are a type of telephone that uses a rotating dial to input numbers. When a user wants to make a call, they turn the dial to the desired number, which generates a series of electrical pulses that connect to the telephone network. This technology was widely used before the advent of push-button phones. The first dial phones were introduced in the early 20th century and became popular throughout the 1950s and 1960s. They are often associated with the landline era of communication. Although largely replaced by modern touch-tone phones and mobile phones, dial phones remain a nostalgic symbol of earlier telecommunications.
