When were rotary phones invented?

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.

Did old rotary phones have area codes for long distance.?
Yes, rotary phones had area codes, beginning in the US and Canada in 1947. In fact, the pattern of area code assignments took into account the time it would take to dial that number on a rotary phone. For example, large cities like New York City, Los Angeles, and Chicago had area codes 212, 213, and 312, respectively. If you add up the number of "clicks" on a rotary dial for those numbers, it's 5, 6, and 6. At the opposite extreme, South Dakota's area code 605 adds up to 21. (The 0 on a rotary dial is 10 clicks.) Places that had a lot of telephone traffic had numbers with lower total clicks.
