Should there be an agency in charge of the Internet? How would business, government, and education be impacted if the Internet w
aksik [14]
I believe the government should not be able to regulate or control the internet. The internet is a place to express and exchange new ideas. And when an agency or government starts to regulate the internet, they can prevent from view certain content.

There is something called net neutrality. Its definition can be found on Google, "the principle that Internet service providers should enable access to all content and applications regardless of the source, and without favoring or blocking particular products or websites." - Google

What that means is, that internet service providers (ISP's) should provide all content without discrimination. For example. There is two ISP's. ISP A and ISP B. ISP B does not practice net neutrality. So, when a customer has ISP B's service, he/she cannot view content from ISP A. Or whatever company or websites ISP B does not want you to view. On the contrary, ISP A practice net neutrality. ISP A provides all content for its customers. Even if ISP A doesn't like ISP B or any websites, it still allows their customers to view that content. 

I support for new neutrality. And so should you.
