"Fun fact: The character Buck Rogers "first appeared in 1929 and is public domain in 2025, but technically the futuristic space hero has already been copyright-free for decades, despite claims that he was still copyrighted," Jenkins writes.
- "This is because the copyright registration for the Buck Rogers comic strip was not renewed, so that its copyright expired after 28 years. Also, the original version of the character was actually introduced in a novella as 'Anthony Rogers' in 1928; that character has long been public domain as well.""
