Apple is currently battling Google in market capitalization. While Apple benefits from the success of devices such as the iPhone and ongoing rumors of new products, Google has taken a huge hit over the past few months. Both companies currently have a market capitalization of about $158 billion.

Apple and Google have left other industry heavyweights behind – such as Cisco ($142.13 billion), Intel ($135.66 billion), Hewlett-Packard ($111.87 billion), Nokia ($97.75 billion), BlackBerry maker Research in Motion ($71.14 billion), Disney ($59.26 billion) and Dell ($50.48 billion). It's interesting to note that the combined market value of Sony, Amazon, Yahoo!, Adobe, Motorola, Real Networks, Palm and Napster is less than that of Apple or Google.

Microsoft and IBM are ahead of the two with market caps of $256 billion and $170 billion, respectively.
