Or perhaps more significantly: for only the second time in 41 years. For an entire generation, works simply didn't enter the public domain: 1921 works became public domain in 1977. Copyright Act extends the term by 20 years in 1978. 1922 works became public domain in 1998. Sonny Bono Act extends the term by 20 years in 1998. 1923 works became public domain in 2019. Were it not for these two extensions, we would today see works from 1963 entering the public domain. Instead, we aren't even up to the first 'talkie' motion pictures.
