4 апр 1876 г. - Invention of the Telephone

Описание:

The first telephone invented by Alexander Graham Bell. This device allowed people to communicate with other people living in a longer distance. This made communication easier between business men during the Industrial Revolution.

My own experience: I have seen the early types of telephones in movies and shows but never really tried this model of the phone. I understand that there are a lot of things that you would have to do when calling someone using the phone and how it was really a game-changer for many businesses.
