Microsoft
Microsoft's ambitions are anything but small. The world's #1 software company provides a variety of products and services, including its ubiquitous Windows operating systems and Office software suite. Microsoft has expanded into markets such as video game consoles, customer relationship management applications, server and storage software, and digital music players. The company has also used selective acquisitions to bulk up its presence in markets such as online advertising, mobile devices, and enterprise software. In 2008 Microsoft made repeated efforts to acquire Yahoo! but was ultimately rebuffed; the two companies would instead sign a deal in 2009 to combine their search operations.
Apple Inc.
Apple aims for nothing short of a revolution, whether in personal computing or digital media distribution. The company's desktop and laptop computers -- all of which feature its OS X operating system -- include its Mac mini, iMac, and MacBook for the consumer and education markets, and more powerful Mac Pro and MacBook Pro for high-end consumers and professionals involved in design and publishing. Apple scored a runaway hit with its digital music players (iPod) and online music store (iTunes). Other products include mobile phones (iPhone), servers (Xserve), wireless networking equipment (Airport), and publishing and multimedia software. Its FileMaker subsidiary provides database software.
