Copyright does not last forever. At some point, every protected work enters the public domain, meaning anyone can use it freely, without permission or payment.
But figuring out when that happens is more complicated than most people expect. The rules depend on when the work was created, whether it was published, and who created it.
The Current Rule is Life of the Author Plus 70 Years.
For works created on or after January 1, 1978, U.S. copyright law sets a clear baseline: Copyright lasts for the life of the author, plus 70 years.
So if an author dies in 2025, their works remain protected until December 31, 2095. Only after that do they enter the public domain.
This is the standard rule for individual creators. But it changes depending on the type of authorship involved.
The Duration Is Different for Corporate and Anonymous Works.
Not every work has a named human author. For those cases, the Copyright Act sets separate timelines:
| Type of Work | Duration |
| Individual author | Life + 70 years |
| Work made for hire | 95 years from publication or 120 years from creation (whichever is shorter) |
| Anonymous or pseudonymous work | 95 years from publication or 120 years from creation (whichever is shorter) |
A corporate training video produced in 2010, for example, would be protected until 2105 under the work-for-hire rule, assuming it was published that same year.
Older Works Follow a More Complicated Set of Rules.
Here is where things get layered. Works created before 1978 do not follow the same rules. Their duration depends on publication date, registration, and renewal, and the rules shifted significantly over the decades.
Works Published Before 1928 Are Now in the Public Domain.
As of January 1, 2024, all works published in the United States before 1928 are in the public domain. That means the novels of F. Scott Fitzgerald’s early career, silent films, and sheet music from that era are freely available for anyone to reproduce or adapt.
Each January 1st, another year’s worth of works cross over. In 2025, works published in 1929 entered the public domain, including early sound recordings and literary works from that year.
Works Published Between 1928 and 1977 Have Varied Protection.
This middle period is the most complicated. Whether a work from this era is still protected depends on several factors:
- Was it published with a proper copyright notice?
- Was the copyright renewed after the initial 28-year term?
- Was it government work?
Many works from this period are actually in the public domain, because their owners failed to renew registration under the rules that applied at the time. Researching a specific work’s status often requires checking the Copyright Office records directly.
The Sonny Bono Act Extended Copyright Durations by 20 Years.
The current 70-year post-mortem term did not always exist. Before 1998, the rule was life plus 50 years. The Sonny Bono Copyright Term Extension Act added two decades and effectively froze the public domain for 20 years by preventing new works from entering it.
Critics called it the “Mickey Mouse Protection Act”, a nod to Disney’s lobbying efforts to keep early Mickey Mouse films protected. That is not a coincidence. Congress has extended copyright terms multiple times since 1790, often in response to industry pressure.
According to the U.S. Copyright Office, the United States has extended copyright duration 11 times in the past 40 years, a record that reflects ongoing tension between creator rights and public access.
Sound Recordings Have Their Own Special Copyright Timeline.
Sound recordings were largely excluded from federal copyright protection until 1972. As a result, they follow a separate set of rules under the Music Modernization Act of 2018:
- Recordings published before 1923: now in the public domain
- Recordings from 1923–1946: protected for 100 years from publication
- Recordings from 1947–1956: protected for 110 years from publication
- Recordings from 1957 onward: protected under standard federal rules
This matters for anyone digitizing archives, licensing old recordings, or producing documentaries that include historical audio.
When a Work Enters the Public Domain, It Is Free for Everyone.
Once copyright expires, the work belongs to everyone. No license needed. No fees. No permission required.
That is why you can read the full text of The Great Gatsby online for free today. It entered the public domain on January 1, 2021. And it is why filmmakers can adapt public domain stories without paying rights holders.
The public domain is not a legal gray area. It is an intentional feature of copyright law, designed to ensure that creative works eventually return to the public that helped sustain them.
