The brands make the business. And in some cases, they’re giant businesses in their own right. Here are three products and subsidiaries of corporate giants that—taken individually—would still make the 500 list, and where they would rank.

On January 9, 2007, Apple aapl made two announcements. The first was the introduction of the iPhone—a product the late Steve Jobs introduced as an “iPod, phone, and internet communicator.” The second was that the company was changing its name from Apple Computer, Inc. to simply Apple Inc.—showing that even before it went on sale the company recognized how transformative to its business the iPhone would become. Today iPhone represents 63% of Apple’s $216 billion revenue.
Maybe just as impressive: Its smaller business units, namely Macintosh, iPad, web services, and “Other” (which includes Apple Watch, Beats and Apple TV), would all be Fortune 500 companies in their own right.

Revenue: $25.483 billion
Berkshire Hathaway brk.a owns everything from ice cream parlors to railroads but there’s only one business Warren Buffett describes as “the company that set my heart afire 66 years ago (and for which the flame still burns)”—car insurance giant Geico. And it’s easy to see why. Geico’s top line has grown 300% in the last 17 years, and has made a profit on its underwriting in each of those years (most insurers are happy to break even on underwriting). Other Berkshire companies that would make the Fortune 500 include BNSF railroad, Berkshire Energy, Berkshire Hathaway Reinsurance Group, and McLane Company.
