Ever heard of "net neutrality"? If you aren't an activist or a corporation that might be affected by the Federal Communications Commission's proposed changes to net neutrality, it probably hasn't crossed your radar.

At least, they hadn't heard of it until this past week, when talk show host and comedian John Oliver set the issue in his cross hairs - and sent tens of thousands of commenters to the FCC's website in support of maintaining current rules. In essence, net neutrality ensures that all traffic on the Internet moves at the same speed. Not sure why that matters? We'll let John Oliver explain it.
