"The new services, called MSN Newsbot and MSN Blogbot, up the ante in the battle for Internet search market share. Microsoft has already said it is working on its own general Internet search engine, expected to be launched this year, to go head-to-head with Google.

Microsoft is claiming a first with MSN Blogbot, a service that will let users search Web logs, or "blogs," personal-journal type Web pages that have become increasingly popular. Many consumers even use blogs as a news source, according to Microsoft.

MSN Blogbot will aggregate content from hundreds of thousands of Web logs and index that content based on which Web logs are most popular and credible, Redetzki said. The service should go into beta soon, and Microsoft plans to introduce MSN Blogbot worldwide, she said.

Microsoft has made Internet search a key investment area and is building its own search engine from scratch. The company's current search services on the MSN Web site are offered through a partnership with Yahoo. "
