Microsoft Corp. introduced a search engine with better shopping, travel and sorting features, an effort to show that Google Inc. can't do everything.

Microsoft CEO Steve Ballmer unveiled the services, called Bing, at a technology conference Thursday in Carlsbad, Calif. The program will be available over the next a number of days, accompanied by the company's first broad advertising campaign promoting a search engine.

Microsoft, the world's largest software maker, has an eighth of Google's U.S. market share in Internet searches, forcing it to find exact niches to exploit. The company is looking for areas where Google doesn't deliver exactly what users want, said Mike Nichols, Microsoft's general manager for search products.
