Newly in the public domain

Today is a great day; in the USA, works written/created in 1922 become available under the public domain as the 1970’s extension laws durations expire. This is recorded by Ars Technica, in an article entitled, Mickey Mouse and Batman will soon be public domain—here’s what that means. This headline is misleading since these properties won’t become PD until the 2030s. Don’t quite get the maths myself since the international treaties talk of 70 year durations and this looks like 95 years but we do know that this was an exercise in corrupt lobbying power but it would seem that “I’ve got you Babe”, written by the Congressional sponsor of the second extension law, yup, they did it twice, expires in 2060; don’t think I’ll be around to enjoy it for free. What a greedy twat!
