How has communication changed in the united states over time

Communication has gotten better.one if the many reasons is because of phones you can call text even FaceTime

Back then people had this thing called a telegram i think. So years later I think someone released a phone (not touch screen). So people lived with boring phones and like in the  late 1900's i think we got touch screen and better TV's and google. And people started to produce more and more like the Iphone 7 
and new games and of course . :3

hopefully this helped.
