In the Seattle Times, there was an article about the Seattle Seahawks not blocking a trademark request concerning the term "District 12" filed on behalf of "Hunger Games" author Suzanne Collins. The copyright issue is alive and well today and something the Seahawks defend - ask someone who tries to copy their famous logo and sell it.
According to Common Sense Media there are several key terms you need to know:
fair use: the ability to use a small amount of someone’s creative work without permission, but only in certain ways
commercial purposes: a use in connection with a business, usually for profit
copyright: a law that protects a creator’s ownership of and control over the work he or she creates, requiring other people to get the creator’s permission before they copy, share, or perform that work
Creative Commons: a kind of copyright that makes it easy for people to copy, share, and build on someone’s creative work – as long as they give the creator credit for it
public domain: creative work that’s not protected by copyright and is therefore free for one to use however one wants
