Cartoon characters have been a beloved part of pop culture for generations, but many of them are still protected by copyright. However, thanks to U.S. copyright laws, characters eventually enter the public domain, meaning they can be used freely for new creative projects, adaptations, and merchandise. If you're a fan of classic animated icons, here’s a look at when some of your favorite cartoon characters will become public domain.
Already in the Public Domain
Steamboat Willie (Mickey Mouse) – 2024
The original version of Mickey Mouse from Steamboat Willie officially entered the public domain on January 1, 2024. While later versions of Mickey (such as the red-short-wearing mascot) remain copyrighted, this classic black-and-white incarnation is now free to use in new projects.
Felix the Cat – 2019
One of the earliest animated superstars, Felix the Cat first appeared in 1919 and entered the public domain in 2019. His mischievous charm and surreal adventures have influenced countless animated characters.
Upcoming & Now Current Public Domain Cartoon Characters
Betty Boop – 2026
One of the most recognizable cartoon icons of the 1930s, Betty Boop will enter the public domain in 2026. Known for her flapper style and catchy tunes, Betty Boop remains a symbol of early animation’s golden era.
Popeye – 2025 (Comic Strip)
While some early versions of Popeye the Sailor have already entered the public domain, additional stories and adaptations—including animated versions—will continue to become available year by year.
Oswald the Lucky Rabbit – 2025
Oswald, an early Disney character and precursor to Mickey Mouse, will be joining the public domain in 2025. This mischievous rabbit was originally created by Walt Disney before Mickey took the spotlight.
Who’s Next? Future Public Domain Characters
Superman (Early Versions) – 2034
The Man of Steel debuted in Action Comics #1 in 1938, meaning the earliest version of Superman will enter the public domain in 2034. However, this will only apply to his first appearance, so later elements like flight and iconic storylines will still be copyrighted.
Bugs Bunny – 2035
One of the most famous cartoon characters of all time, Bugs Bunny made his debut in 1940 and will be free for public use starting in 2035. However, as with Mickey, only the earliest version of Bugs will be available for unrestricted use.
Donald Duck – 2036
Created in 1934, Donald Duck will enter the public domain in 2036. His short temper and iconic sailor outfit have made him one of Disney’s most enduring characters.
Why Does Public Domain Matter for Cartoons?
The public domain ensures that classic animated characters can be reimagined, remixed, and introduced to new generations. It allows artists, filmmakers, and writers to create fresh stories while preserving the cultural impact of these legendary cartoons. The arrival of Steamboat Willie Mickey Mouse into the public domain in 2024 has already inspired independent films and creative projects, showing how public domain characters can spark new artistic expression.
As we look forward to Betty Boop, Oswald the Lucky Rabbit, and Popeye joining the public domain soon, one thing is clear—animation history is becoming more accessible than ever!
