Doesn't copyright expire after 50 years or something. I heard that one media company in another country recently had some laws changed to extend copyright to hundreds of years, after some of their valuable material was due to soon come out of copyright. They have some high up and powerful people.
Life of the author + 50 years. The US is/has extended that to +70 years.
I think mickey mouse stuff was due to come of of copyright soon.
Last time it was about to come out of copyright the US Gov extended it.. They will again this time to something like 200 year..
