(NEW YORK) -- Just how big has electronics company Apple become?
Well, for a short time Tuesday, it surpassed Exxon Mobil Corp. as the most valuable company on the planet.
During another wild day of trading on Wall Street, Apple's market capitalization reached $343 billion, briefly topping Exxon Mobil's, which slipped to a mere $334 billion. Market capitalization is the total dollar market value of all of a company's outstanding shares.
Even as the oil giant retained its top spot, though only by $2 billion, there's no denying the power of Apple. Since introducing the iPod a decade ago, shares in the company have jumped an astronomical 4,000 percent, while the stock value has tripled since 2007 due to the advent of the iPhone.
Exxon Mobil, which is still doing pretty well for itself considering, has seen its shares drop by about seven percent lately because of sliding oil prices.
