This seems like one of those terms without any clear origin, and the Wikipedia doesn't list this potential use as one of them. I'm not saying it isn't true (I don't know), but @Quilotoa@lemmy.ca you could edit the title to something like "the term 'blockbuster' may have come from". Or even just add "[disputed]" to the title
