The article doesn't state what "record" the sales set nor does it split the increase in sales of D&D from that of Magic: The Gathering. All it states is that ALL of Hasbro's games, including Monopoly and Jenga, were up 15% in 2020 from 2019.
I'm am surprised that games represents 32% of Hasbro's overall sales. That's much higher than I would have expected.
They have said, repeatedly, in interviews that revenue from D&D is up over 30% from last year, and last year was up strong (they put a number on it i just don't recall) from the prior year, and that every year since the release D&D has oldsold the prior year.
I had posted this elsewhere, but it's a nice comparison snapshot of the #1 RPG, and the #2 RPG, concerning Amazon sales:

Hasbro isn't going to sell D&D and the "fad" might not fad. Instead, the plan (which looks possible right now) is to come out with the movie and leap the next step. Not as strongly as Marvel comics did, but unquestionably Marvel comics went from "fad" in terms of comics to "pop culture icon permanently" in a matter of a few years once the movies started to come out. D&D won't succeed that well, but it definitely can take the next leap into pop cultural acceptance rather than simply fade back as a trend that ebbs.
