I thought copyrights were for 100 years?
In the US, since the Sonny Bono Copyright Term Extension Act went into
effect a few years ago, the term is 70 years beyond the death of the
author, or 95 years from creation for works of corporate authorship.
However, over the last 40 years or so, Congress on average every
year increased the term by a year. The Supreme Court has now ruled
that they are allowed to retroactively increase the copyright term,
so it is now effectively unlimited, as long as Disney et al. continue
lobbying for increases. :-(
