I, too, live above the Mason-Dixon line and I've never heard of Prime either. But maybe this has less to do with geography, and more to do with the media that we allow ourselves to be exposed to. For instance: I haven't watched regular advertising-supported TV (OTA or streaming or otherwise) for at least a decade, and my general online experience (including with things like YouTube) is generally completely ad-free (thanks, Sponsorblock and uBlock Origin). I am, very purposefully and intentionally, rather "out of the loop" when it comes to advertising for trendy things.
