Google's book search faces antitrust concerns

Google (GOOG) seems to be the market share leader in almost every business it enters, from search to mapping. Of course, its online payment offering has never taken much business from PayPal. But as is the case with most companies that have a lot of power over any industry, antitrust regulators lurk around every corner.

It looks like Google will face more scrutiny about the way its does business, just as other market leaders in their respective industries such as Microsoft (MSFT) and Intel (INTC) did before it.
