Why were video cameras invented?

So people could capture good moments, use it for security cameras in shops for thief's make movies and start careers with the movies, it could also entertain people more and more things could be made up with jobs and money.

I think the video camera was invented so that we could capture special moments in time where just photographs werent enough to capture the essence of the moment. For example a wedding, christening or holiday etc. Also, a lot of people like to make homevideos and some use this to start off a career that they would like in camera work areas.
