Thanks to U.S. copyright laws, nothing has entered the public domain in nearly 40 years.

"No copyrights have entered the public domain in the United States since
1978, and no open source intellectual properties will become available
until 2019, when we'll finally have access to things from 1923. Yay?"

Upworthy on the value of the public domain.
