The modern touch tone push button dial was first introduced in 1963. Before this was introduced many homes around the world had rotary dial phone which to some people was time consuming. However the touch tone push button was more expensive at the time and since the rotary dial had been used by most people since the 1930's, most people stuck with the rotary dial. However by the 1970's the touch tone push button phone was more popular especially in businesses.
