Shower thought for the morning was: why is cream cheese spread ‘Philadelphia’ called that? Is it from Philadelphia? (My box isn’t, of course: it came from Ireland.)
Nope, it turns out that it was originally invented in New York in the 19th century and named for Philadelphia because Philadelphia, PA was at that point famous for its dairy industry. Just another bit of parasitic branding leveraging a borrowed association, like the Quaker Oats guy or the Rolls Razor. Now I’m wondering how many other examples I can find!
