DoubleClick ( DCLK) agreed to acquire closely held SmarthPath in a bid to expand its online marketing reach. Terms of the all-cash deal weren't disclosed, but DoubleClick spoke highly of the move. "The acquisition of SmartPath is a critical step in DoubleClick's plan to become the premier provider of marketing solutions that help empower companies to manage their increasingly complex marketing environment," said President David Rosenblatt. DoubleClick said SmartPath's solutions are designed to help marketers and their agencies manage the operational aspects of marketing, including strategic planning, project management, workflow, document management and marketing financial management. Marketing resource management provides a common operating platform for marketers to plan and develop campaigns and budgets across all marketing channels, the company said. The move comes a day after DoubleClick released its annual Touchpoints study, which the online marketer said shows that interactive marketing is exerting a "growing influence on further learning and purchase decisions." DoubleClick shares closed Monday at $11.
