DC also had royalty agreements on good-selling stuff from 1976-1996, meaning they need to pay more for some reprints. If a planned reprint doesn't hit a sales target, it geta cancelled.
Marvel doesn't really do royalties like that, and everything was work-for-hire during that same time period (except for creator owned Epic stuff). This lets them print anything they want, especially since Disney doesn't seem to pay attention to what they do. AT&T bought WB (DC) last year, and the trade department got overhauled (with one executive being fired).
