I do recall a handful of the full-page PopSci "back of the mag" ads being articles in their own right, and sometimes they were as well-written as the actual articles written by PopSci. Although those were always the exception, rather than the norm, I feel like that kind of thing is just gone. That said, I wonder if it's caused by limits in the ad delivery methods we use today, rather than some industry wide lack of interest in making quality ads. I can't conceive of how such an ad would be delivered through Google, for example. Meta? Maybe.
