A rotary phone works by basically hanging up and picking up rapidly, and this would send pulses of electricity to equipment at the central office, which would move machinery there to make your call. Therefore, it was called pulse dialing. Today, we use tone dialing.

Who changed the telephone from the rotary dial to pushing the buttons?
Technology drove the change. The rotary dial acted as a timer for a switch to open and close a circuit the right number of times to indicate a number. 1 pulse meant the number 1. 9 pulses indicated 9 of course. The rotary dial was easy to manufacture and was reliable. Exchanges were huge electro-mechanical systems that were designed to respond to the streams of pulses from telephones. As telephone exchanges were developed, they could accept a twin tone as a number identifier and it is much easier to use a keypad to generate the tones than a rotary dial, hence the move to push-button phones. The earliest push button phones were a combination of the two: They would offer the user a set of buttons, but internally, pushing a button would generate the same pulses that a rotary dial would create.
What phones are not used today?
The old fashioned rotary dial telephone has almost completely fallen out of use. The touch tone phone is tremendously more convenient.
