> A website — graphics, content, visual elements — is copyrighted at the time of development. So putting the copyright notice on the bottom of a site states that the material displayed is not to be used without permission of the owner. In fact, you don’t even need the notice to claim copyright; the law eliminated the requirement of public notice in 1989.
