Microsoft has agreed to acquire ScreenTonic, a mobile advertising firm based in Paris.

ScreenTonic's offerings are designed to provide advertisers with a range of ad formats, from display to text, as well as ad management and reporting capabilities.

Microsoft said that the acquisition will allow it to better target adverts at audiences across multiple digital devices, including PCs, Xbox video game systems and mobile phones.

"The mobile internet is an extraordinary vehicle for brands to connect with their target audiences because devices like cellphones enable interaction virtually anywhere or anytime," said Steve Berkowitz, senior vice president of the Online Services Group at Microsoft.

"The acquisition of ScreenTonic will be part of our long-term strategy to deliver ad experiences that map to the environment.

"Together, we will be able to provide relevant ads where consumers are, when they are actively engaged and communicating."

Under the terms of the acquisition ScreenTonic will continue to operate from its current headquarters in France. Financial details were not disclosed.
