What copyrights have expired?
Could you please elaborate on the specific context in which you're asking about expired copyrights? Are you referring to a particular work of art, literature, music, or software? Or are you interested in understanding the general principles behind copyright expiration? In general, copyright laws vary from country to country, but most jurisdictions have provisions that allow for the expiration of copyright protection after a certain period of time. This period can range from several decades to the life of the author plus an additional period. Once a copyright expires, the work enters the public domain, meaning it can be freely used, copied, distributed, and adapted by anyone without the need for permission from the original copyright holder. So, if you're asking about a specific work, it would be helpful to know more about the country of origin and the year of creation to determine if the copyright has expired. If you're looking for a general understanding of copyright expiration, I can provide an overview of the principles and how they differ across different jurisdictions.
