Educational Technology and Copyright Law

From the article Educational Technology and Copyright Law, I learned that almost everything is copyrighted from the moment it is made.  Anyone can choose to use whatever was made as long as it is for nonprofit educational use.  The only time you need to get rights to something is if said something is licensed, in which case the maker has certain specifications that must be met in order for their product to be used.  So basically, anything that is your original idea is copyrighted, but not everything is licensed.
