What is net neutrality?
Net neutrality calls for fair and equal access to any site on the internet.
Net neutrality effects how content is delivered on the internet. Without regulation, internet service providers (ISP) are allowed to give higher priority access to certain sties.
Because of the strong history of internet traffic tracking, ISPs have vast quantities of data that they can use to determine which sites are valuable and make side deals with those sites.
