I noticed today that when I log in to my British iTunes account on my iPhone that the header reads "Christmas." But when I switch back to the American account, it reads "Holiday."
Lame. Especially considering there aren't any Hanukkah apps in that category (Eid is long over), so there's no reason to call it "Holiday." Is there some atheist middle manager at Apple in California who thinks he's going to magically burst into a fit of Bible-thumping and foot-washing if he sees the word "Christmas?"
It's a noun. It's a thing that exists. Get over it. Apparently the people at Apple UK have.
Here's the screenshots. iTunes UK on the left, iTunes US on the right.
