You'd expect America to be the standard banner for Net Neutrality, but we have to look to South America to find the very first country to get the job done. That country is Chile, according to a SlashDot report. Chile representatives voted for new net neutrality rules by a margin of 100 - 0. According to Slashdot, the rules read like this (a rough translation):
"No [ISP] can block, interfere with, discriminate, hinder, nor restrict the right of any Internet user of using, send, receive or offer any content, application, or legitimate service through the Internet, as well as any activity or legitimate use conducted through the Internet."
The law also has articles that force ISPs to do other things like require parental control tools, clarify contracts, "guarantee" user privacy and safety, and not to restrict any liberty whatsoever.
