Fiscal year ends differ, so this is not a comparison of the same year. Revenue is taken from whichever element the company itself uses (Revenues and so on), so its scope can differ between companies. Finance (SIC 6000s) defines revenue differently from other industries, so its ★ marks and medians are built among finance companies only. This is not a ranking. It is simply sorted by revenue, largest first.
