Google will begin selling ads on some cable networks owned by NBC Universal in a new partnership that will expand Google's efforts to become a force in television advertising.

Under the agreement, NBC Universal will make a relatively small amount of advertising time on networks like MSNBC, CNBC, Sci Fi and Oxygen available for sale through Google's TV Ads program in the coming months, the companies said. The partnership could later be extended to other NBC Universal properties.

Microsoft's aggressive campaign to increase its position in digital advertising took another step this week as it announced the acquisition of Navic Networks, a television advertising provider. Terms were not disclosed.

The deal, announced Tuesday, will give the software giant ownership of Navic's sophisticated campaign-management tools for digital advertising. Those tools optimize where and when interactive television ads are placed. One tool, called Admira, offers a unified ad network so that selected audiences can be targeted across all ads in a campaign.
