Google plans to launch <A HREF="http://www.businessweek.com/ap/financialnews/D8OIK1K01.htm">software similar to Microsoft's popular PowerPoint program</A> as the two companies vie to dominate the online experience.

Google Chairman and Chief Executive Eric Schmidt described the software Tuesday at a conference for Internet entrepreneurs. He also blasted Microsoft and AT&T, whose executives complained over the weekend that Google may soon have an illegal monopoly in online advertising.

Google announced Friday it would pay $3.1 billion to acquire ad-management technology company DoubleClick. Almost as soon as Google announced the cash acquisition, Microsoft and AT&T executives said the deal could violate antitrust legislation--and result in a dangerous concentration of Internet users' personal data at Mountain View-based Google.
