An expiry of copyright - after which a work enters the public domain - would accomplish this rather nicely without completely disincentivizing content creators.
Unfortunately, while this is already the case in theory in many jurisdictions, it's not the case in certain others, where the duration of copyright is effectively set to "current year minus first appearance of Mickey Mouse plus twenty years" thanks to the interests of a particular company whose name rhymes with a "D" and ends with an "isney". :)
