Betty Boop, More Mickey Cartoons to Enter Public Domain

Betty Boop, the flirtatious cartoon flapper who first appeared nearly 100 years ago, is nearing a major legal milestone. On Jan. 1, 2026, the character’s earliest incarnation will enter the U.S. public domain, meaning it can be reused, reimagined, or remixed without licensing fees. Axios reports that Betty Boop is part of a larger group of works from 1930 that will soon become free for public use.

Also entering the public domain are nine early Mickey Mouse cartoons, including shorts featuring his dog Rover, a precursor to Pluto. Other notable additions include the 1930 film adaptation of All Quiet on the Western Front and the Marx Brothers comedy Animal Crackers.

Several well-known books will also become freely available. Among them are William Faulkner’s As I Lay Dying, Dashiell Hammett’s The Maltese Falcon, and Agatha Christie’s The Murder at the Vicarage. Children’s classics such as The Little Engine That Could and the first four Nancy Drew mysteries are included as well.

IndieWire notes that most creative works enter the public domain after 95 years, though sound recordings generally take 100 years. As a result, a number of influential musical recordings from 1925 will become public domain in 2026, including Marian Anderson’s rendition of “Nobody Knows the Trouble I’ve Seen” and Bessie Smith’s “The St. Louis Blues” featuring Louis Armstrong. Musical compositions like “Georgia on My Mind” and “Dream a Little Dream of Me” will also be open for adaptation.

Duke Law professors Jennifer Jenkins and James Boyle, who track public-domain releases annually, say the expanding pool of shared cultural material plays a vital role in creativity. “To tell new stories, we draw from older ones,” they wrote, describing this group of works as especially significant. Jenkins told NPR it may be her favorite year yet for public-domain releases.

However, there are important limitations. Only the original 1930 versions of characters and works are entering the public domain; later versions remain protected. In addition, trademark law can still limit how names, images, and designs are used commercially.

At the same time, legal experts warn that enthusiasm over new public-domain material is overlapping with unresolved issues surrounding artificial intelligence. As AI systems are trained on massive collections of copyrighted content and Congress has yet to modernize relevant laws, many of these conflicts are expected to be decided in court rather than through new legislation.
