It's interesting to me that people are so reluctant to change these sorts of things, even if they seem minor to those people.
The stated reasons what's his name the owner had for keeping the name basically amounted to brand-building. It's apparently going to cost the Washington Godknowswhats a fair amount of money as far as merch and stuff. (The situation isn't the same as, say, whoever makes Lucky Charms having to change the name to something else, but it's kinda similar. In that instance all the money they've poured into creating a brand vanishes.)
Of course, they could have saved themselves the now even bigger hassle/PR loss if they'd changed the name five years ago.
