.george is a pretty funny one. apparently Walmart owns it, so you probably won't be able to register a .george domain any time soon. https://icannwiki.org/.george do companies even use these in the wild or are they buying these TLDs for nothing? ".brother", ".canon", ".nokia", ".panasonic", ".playstation", ".xbox", ".xerox"... there's even ".sandvikcoromant", which is some sort of Swedish metalwork company.
George is the clothing brand of the ASDA supermarket chain in the UK, which Walmart used to own. I'm not sure if it's a brand they use worldwide though; I don't really go to Walmart when in the US. Either way, that's why they own it, presumably.
There was also a George magazine, which... I think belonged to RFK (Senior)?
