Where do Genres come from?

In the beginning men tried to communicate with one
another. Now the media earth was formless and
empty, darkness was over the networking
systems of the deep, and the thoughts of man were hovering about them.

And then one man said "I have this idea" and he sent it out through the networking system. Through this system the idea reached many people, and the man saw that it was good.

And then Over time many other people sent messages out through the system of communication, and even discovered new networks for sending their messages. The people did this and found that it was good.

And then one man said "through networking I can send specific ideas to the people who care about those ideas the most." This pleased the people who recieved the messages, and they communicated back with a response to the message, making it's theme even more speciffic. This was the beginning of
genres.

It is an accepted idea that people flock to groups and things they are comfortable with or interested in. I believe, as explained through narritive above, that genres developed as a result of people with commonalities communicating with eachother. Through communication they formed even more speciffic groups and styles of thinking, art, music, tv, etc.
