Copyrights do not last forever.
If created on or after January 1, 1978, U.S. copyright law automatically protects an original work (including digital content on websites) that has been fixed in a tangible medium of expression. This includes but is not limited to text, videos, and photographs. The copyright term starts at the moment of creation and lasts for the author’s life plus an additional 70 years. For a joint work prepared by two or more authors who did not work for hire, the term lasts for 70 years after the last surviving author’s death. For works made for hire and anonymous and pseudonymous works, the duration of the copyright is 95 years from first publication or 120 years from creation, whichever is shorter (unless the author’s identity is later revealed in Copyright Office records, in which case the term becomes the author’s life plus 70 years).
