This should be the top (and only IMO) priority of CC enforcement instead of going after sci-hub and the like.

> We find that almost all books, regardless of category, peak in the first 15 weeks after publication

Seems that 2 years after publication the number of copies sold per week declines by two orders of magnitude compared to the peak.
To me, 5-7 years seems reasonable for technology inventions (patents), 7-10 years for books and other art.
Stephen Breyer, the recently retired Supreme Court Justice, wrote an interesting article in 1970 back when he was a law professor about that, called "The Uneasy Case for Copyright".
In it he argued that cut-rate copies swamping the market did not actually happen historically. Books made most of their money fairly shortly after publication. Copying technology was slow enough that by the time someone could get copies made and distributed there wasn't much market left for the book anyway. (Also, there weren't huge booksellers with massive inventory, or book on demand services, further making it harder for a book to get much sales after the first printing).
Now copying technology is a lot faster, and we do have huge booksellers like Amazon and book on demand services and we have ebooks so there is pretty much no cost to keeping a book available indefinitely, and so most of Breyer's points are no longer applicable even if they were possibly correct in the 19th and much of the 20th centuries.
Theoretically there is a 100 years copyright on StarCraft but I doubt a lot of people will buy it on GoG in 2050.
