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.
