As Google Builds Out Own Content, Some Advertisers Feel Pushed Aside

Google is transforming its core business, and the basic notion of search: Providing as much information as possible to keep users in Google's virtual universe.

Google is less a Web index and more an Internet destination, offering content and commerce within an ever-growing array of Google services. Its transition promises to be a tricky one for its own business and for millions of others dependent on its search results to survive. Advertisers will pay more than $50 billion to the search giant this year for clicks that deliver potential customers to their Web pages. By offering its own hotel listings, for example, Google may alienate advertisers such as online-travel agencies that alone pay it billions a year.
