Burger King just released a three-minute "social experiment" video that explains net neutrality using burgers and, well, you should just probably watch it.
In the video, real Burger King customers are forced to either pay more for a burger to get it quickly or pay the normal price and wait for a long time.
Basically, in this example, Whopper = internet.
Before the Federal Communications Commission repealed net neutrality regulations in December, these rules prohibited internet providers from blocking or slowing websites, or charging a premium for "fast lanes" for specific services or higher-quality streaming.
