Fortune 500

Not that it means anything beyond bragging rights, but if you're fixated on the positions of domestic automakers on the annual Fortune 500 list, both General Motors and Ford are still on it but they've slipped a couple of notches. The list ranks American companies and they're ordered solely by revenue. GM, fifth last year, came in seventh, while Ford fell from ninth to tenth even though both companies saw small gains in annual revenue.

GM's $152.3 billion in revenue was less than a third of that of the first company on the list: Wal-Mart, which regained the title from Exxon Mobil. Berkshire Hathaway and Apple are the firms that moved GM down. Ford, displaced by energy company Valero, had $134.3 billion in revenue.

On a side note, profitability isn't a factor, but both GM and Ford were down in this year's list compared to last year's: GM declined from $9.2 billion to $6.2 billion, Ford fell from $20.2 billion to $5.6 billion. If profits were included, Exxon Mobil would probably still be king: although the energy company made almost $20 billion less in revenue than Wal-Mart's $469.2 billion, it posted $44.9 billion in profit compared to Wal-Mart's $17 billion.
