In terms of communication, the biggest advance has to be the telephone, allowing people the ability to talk in real-time regardless of distance. To use even more advanced technology, the smart phone provided even more ways to communicate. For example, the ability to text or video chat has provided people with even easier/more personal ways of communicating. Hope this helps!
