Google plans to launch software similar to Microsoft's popular PowerPoint program as the two companies vie to dominate the online experience.

Google chairman and chief executive Eric Schmidt described the software at a conference for Internet entrepreneurs.

He also blasted Microsoft and AT&T, whose executives complained that Google may soon have an illegal monopoly in online advertising.

Google announced earlier it would pay $3.1 billion (¤2.29 billion) to acquire ad-management technology company DoubleClick.Reuters
