Copyright holders have rights. Their material (including film, images, photographs, and electronic work) can not be copied without their permission. The copyholder rights are as follows:
After a specific period of time a copyright expires. As of our last Copyright Term Extension Act in 1998, the term of copyright is now the life of the author plus seventy (70) years. If it an anonymous work or a work that belongs to a company, for example, the term is ninety-five (95) years from publication or one hundred twenty (120) years from creation, whichever is shorter.
Unpublished works enter the public domain 70 years after the creator's death.
