What is Net Neutrality?

What is Net Neutrality and why is so important for us to understand about it, things are really changing and the interest created around it are huge, recently I have reading about these but it not yet a popular topic people can talk about; in my opinion if this is going to continue this way, we will lose our freedom to do want we want with the internet without notice that. Here you can watch a really good explanation about Net Neutrality and the opinion Sir Tim Berner, the creator of internet, has about it.
