"way too many" sure suggests that they didn't have cumulative effect. If they have some fixed chance of effecting change, but aren't cumulative, then more is better, but raising that chance is more important. From your story, I'd guess that videos were important, but something else was necessary, too. So it seems very plausible that we are saturated in videos. (Did "Kissing Hank's Ass" stay with you for years, or did you manage to forget it?)
