Internet Companies Plan to Testify Against Google

Three Internet companies -- Nextag Inc., Yelp Inc. and Expedia Inc. -- are gearing up to attack Google Inc. on Capitol Hill, claiming the company is taking new profits for itself by unfairly punishing them on its search engine. In a preview of a Senate antitrust hearing on whether Google abuses its dominance on the Web, representatives of the sites -- which help people search for information on consumer goods, local businesses and airline flights -- said in interviews  that Google has increasingly sought to drive people who use its search engine to its own specialized sites that compete with theirs.
