LONDON: Media buying and market research group Aegis has bolstered its online offering with the purchase of ad-serving specialist for $12.5 million (€9.3m; £6.25m).

Alongside internet ad placement, Bluestreak - which operates in the UK, US, France and Germany - offers a range of tools from the delivery of rich media to campaign evaluation. It will be integrated into Aegis's existing digital unit, Isobar.

Aegis ceo Robert Lerwill said: "While we will continue to work with other industry ad-servers, owning our own technology in-house will give us a step change in product development across both search and display."
