This depends on the type of work or performance. For literary, musical, dramatic and artistic works, a copyright lasts from the creation of the work in question until 70 years after the death of the copyright owner. Other works, such as broadcasts and non-creative films, this is reduced to 50 years from creation. For typographical arrangements this is reduced further to 25 years. Note too that for some works such as performers’ rights and sound recordings, the standard is 50 years, but if the sound recording for either is recorded during that time frame and played in public or broadcast, copyright extends to 70 years from that year.
