Fortune 500 is an annual ranking of the world’s top corporations based on revenue. Apple Inc. (NASDAQ:AAPL) showed an 11 spot improvement with 2012 revenue totaling US $156.5 billion.

Apple Inc. (NASDAQ:AAPL) has become the highest-ranking technology company in a list topped by Wal-Mart Stores, Inc. (NYSE:WMT). The retailer Wal-Mart reclaimed the top spot in the Fortune 500 in 2012 after slipping to No. 2 last year. Major oil companies, including Exxon Mobil Corporation (NYSE:XOM) and Chevron Corporation (NYSE:CVX), Phillips 66 (NYSE:PSX), along with Warren Buffet’s Berkshire Hathaway Inc. (NYSE:BRK.A) (NYSE:BRK.B) separate Apple from the top spot.

Other notable tech companies like AT&T Inc. (NYSE:T) (US$127.4 billion) and Hewlett-Packard Company (NYSE:HPQ) (US$120.4 billion) placed 11th and 15th, respectively, while Microsoft Corporation (NASDAQ:MSFT) (US$73.7 billion) landed in 35th.

The innovation icon is now bigger than ever, but it’s a high-pressure job being king of the hill. During Apple’s press event this past October, it maintained more than disrupted with its software upgrades and iPad mini announcement.

Apple Inc. (NASDAQ:AAPL) CEO Tim Cook had to apologize a lot in the past year- once in September for the failure of Apple’s maps app and then to Chinese consumers this April for slow repair services.

Notably Facebook Inc (NASDAQ:FB) has for the first time made the Fortune 500. It was previously ranked 598, but this year, it was able to take the 482nd spot in Fortune’s listing.

Apple Inc. (AAPL) on Barron’s list:

Interestingly, Apple Inc. (NASDAQ:AAPL) topped this year’s Barron’s 500 list. Though Apple’s stock might be losing altitude and cachet, its stellar operating performance finally has catapulted the company in the No. 1 spot in the Barron’s 500, up from No. 2 in 2012 and No. 4 in 2011. With terrific sales growth and wisely deployed cash flow, Apple turned out to be a winner in Barron’s annual ranking.

According to Fortune, even though Apple’s been faced with overseas labor issues, an apology-inducing Maps app, as well as whispers that the company may not be as innovative as it once was over the past year, it is still doing rather well for itself.
