It is 2016. In the US people have been coming up with business names for over 2 centuries and buying domains to match those names for more than 20 years.
It isn’t surprising, that after doing your research and narrowing down a name for your business that isn’t already taken, the chances of being able to match it with a .com are slim. Unless you come up with a fully made up name. You know, like Kodak or Xerox … words that seem to have come straight from outer space.
