THE MOST IMPORTANT INVENTION

Hi again,

 Today we will write a new post.

This post will try plenty of the most important invention in history.

For me the most useful invention is internet.

It is a global phenomenon , closely linked to communication, but greatly influences on almost all areas of society. They could hardly have imagined that in just its creators 20 years would be such a vital invention as the telephone or television.
