Final answer:
The question pertains to the length of copyright protection, which for individual authors is their lifetime plus 70 years after death, and for works made for hire, anonymous, or pseudonymous works, it is 95 years from publication or 120 years from creation, whichever is sooner.
Step-by-step explanation:
Based on the information provided, the question relates to the duration of copyright protection. For works created on or after January 1, 1978, copyright duration is generally the life of the author plus 70 years after the author's death. If the work is a joint work, the term is 70 years after the last surviving author's death.
For anonymous or pseudonymous works and works made for hire, the copyright lasts 95 years from publication or 120 years from creation, whichever is shorter. This extension, which lengthened the protection for works owned by individuals from 50 years to 70 years post-death, impacted a large number of works including books, movies, and songs.
