For example, a lot of research in computer graphics
Which is a very young field (first article published in late 1960's? the term was coined in 1960, Ivan Sutherland started in 1959 or so on MIT's TX-2), so is not necessarily indicative of all fields. The researchers mean age also tends to be lower, with many professors and professionals not being as badly affected by the greying of labour force in general (or in tenured professorship).
I don't think it's my imagination: the number of recent graphics papers with substantial contributions behind ACM paywalls seems to be dwindling fast.
Reference? Not disputing at all, just haven't noticed such a trend personally. I do know that many academic comp.graphics types do make their papers available, but industry contributors are still mixed, I imagine in part due to their companies own damn lawyers who don't want to lose a potential patent or revenue stream. I don't believe Ken Penlin, Ed Catmull, or Ivan Sutherland's papers are (officially) freely available.
While Computer Science itself is modern field, and computer graphics has a short history, they also are computing pioneers in personality, of whom most are early adopters of Internet technology and culture.
