Microsoft was founded by Bill Gates and Paul Allen on April 4, 1975. Microsoft is the world’s largest software maker measured by revenues. It is also one of the world’s most valuable companies.
When Microsoft went public and launched its initial public offering (IPO) in 1986, the opening stock price was $21; after the trading day, the price closed at $27.75. As of July 2010, with the company's nine stock splits, any IPO shares would be multiplied by 288; if one was to buy the IPO today given the splits and other factors, it would cost about 9 cents!
Standard and Poor's and Moody's (the big two credit-rating agencies) have both given a AAA rating to Microsoft, whose assets were valued at $41 billion as compared to only $8.5 billion in unsecured debt. Consequently, in February 2011 Microsoft released a corporate bond amounting to $2.25 billion with relatively low borrowing rates compared to government bonds.
For the first time in 20 years Apple Inc. surpassed Microsoft in Q1 2011 quarterly profits and revenues due to a slowdown in PC sales and continuing huge losses in Microsoft's Online Services Division (which contains its search engine Bing). Microsoft profits were $5.2 billion, while Apple Inc. profits were $6 billion, on revenues of $14.5 billion and $24.7 billion respectively.
Microsoft is also ranked on the 17th place in Greenpeace’s Guide to Greener Electronics.
