Yahoo's new acquisition is defined as a move to boost its hold on the display advertising market. Dapper, which was founded in 2006, was specialized in creating interactive Web advertisements. It also operates as a technology platform for display ad creation and optimization.
"Dapper's capabilities combined with Yahoo!'s already deep consumer insights will further enhance Yahoo!'s ability to deliver customized and relevant advertising," describes Yahoo's statement on acquisition.
Yahoo claimed that this acquisition will help them to more efficiently deliver dynamic and personalized ads for customers across more of their network.
"The Dapper team is thrilled to be joining Yahoo!, already the largest and most successful force in display advertising," said James Beriker, Dapper President and CEO.
The financial terms of the acquisition are not yet revealed.
