According to BusinessWeek's list of "The World's Best Companies," pretty great! Nintendo is ranked first on the list of 40 companies with "a commitment to innovation, diversified portfolios, aggressive expansion, strong leadership, and a clear vision for the future," based on a metric involving growth rate and percentage of business done outside of the company's home region. In second and third place: Google and Apple.
If you can't be assed to read the quote, they named Nintendo the "World's Best Company" because they print money and tons of it. Post your response to this in the comments!
