The subsegment needs to be easily identifiable—meaning if I had to create a list of prospective buyers, I could figure out a way to do that. For example, I can easily make a list of companies that have more than 1,000 employees by searching the internet for company size info, or a list of Pokémon fans by looking at active users on fan sites or email groups. I would have a much more difficult time creating a list of companies that value design or happy people.
