I have a friend who set up a .com website for his film company using his company's name. He then bought the domain in every available TLD (including .xxx even though he makes mainstream films not adult ones) to prevent anyone using his company name for nefarious uses. I have not seen him in a long while, but the next time we meet up I must remember to ask him if he now owns 1000 domains to cover all the new TLDs.
