It seems there are two kinds of company names. Some, like Ford Motor Co, tell you what the company does. Abercrombie and Fitch tell us the founders’ names, and suggest that while they have passed, their company deserves our trust. Others like Google or Zoetrope coax you out of the left brain, make you poke around for the spirit that drives the company.
