This document discusses copyright and trademark issues related to technology and the internet. It covers several key points: 1) Copyright law protects original works immediately upon creation, whether published or not. Everything published online since 1989 is automatically copyrighted. 2) Trademarks can be advertised online through keyword advertising, but this has led to legal issues if competitors purchase keywords to divert traffic. 3) YouTube agreements with media companies exempt it from liability if it removes infringing content promptly, allowing user uploads while protecting copyrights.
