The advent of the Internet - find some ideas

Write a composition of about 250- 300 words on the following topic.
'The advent of the Internet is a twentieth-century change that has strongly affected our life.'
( Use your own ideas, knowledge and experience and support your arguments with examples and relevant evidence)

The twentieth century saw great change. The advent of the Intermet should be remembered about the twentieth century:
_It brodens our knowledge by opening a new window on the world
_ It helps us to communicate with each other
_ It has a great influence on our mind

I think of the three ideas but they aren't good enough. Also can you give me the support for examples?
Thanks very much for your consideration!

Your essay should be all about examples. You can refer to the effects it had on business, education, entertainment, and news. This is a vast subject with plenty of room for you to cite excellent sources. The important thing is to make sure the essay has a clearly stated "main idea."

Can you suggest me an example? Thanks

How about online learning, or company websites...
