Video calling is a technology when you call somebody. You see him at the same time. It is a normal thing for us today. People do not know it one hundred years ago. People first get the idea of video calling in the late 1890s.
They do not know how to do it. The first success is in the 1930s. But the video is very bad. A US company makes a Television-Phone in 1955. People see each other when they call. The screen is 25 centimeters wide.
The Internet changes video calling in the late 1990s. It is fast and the picture is good.
Many people use video calling every day. They work from home or they must stay at home. They are happy that they can see their family and friends on the screen.
Difficult words: technology (how people do something and what they use it for), success (when you do something and the result is very good), screen (a flat part of a TV, PC, or phone which people watch).
