Upon the close of the deal, CMGI said it intends to combine its investment in Adtech with AdForce, another provider of advertising services to Web companies. CMGI bought AdForce in September for $500 million in stock.
Adtech will lead European operations for AdForce, Andover, Mass.-based CMGI said in a statement.
Financial terms of the deal were not disclosed.
Adtech joins a string of companies CMGI has acquired or made investments in this year, such as Web portal AltaVista, free ISP 1stUp.com and instant messaging software developer Tribal Voice. CMGI also holds minority stakes in companies within the investment portfolio of @Ventures, the company's venture capital subsidiary.
Earlier this week, CMGI announced plans to acquire Equilibrium for an undisclosed amount. With Equilibrium, CMGI said it is looking to beef up its content delivery infrastructure throughout its network of Web sites. Equilibrium develops software that automates the way sites publish and update content.
"The Adtech acquisition and merger with AdForce is yet another step in our ongoing strategy to solidify CMGI's competitive position in Europe and the international Internet marketplace at large," David Andonian, president of corporate development at CMGI, said in a statement.
