24/7 Media

One of the largest early digital advertising networks and ad serving platforms, later acquired by WPP Group

24/7 Media was one of the earliest and largest digital advertising networks, founded in the late 1990s during the dot-com boom. The company provided ad serving technology, network representation, and digital advertising solutions connecting advertisers with online publishers. It operated one of the largest online advertising networks of its era, competing directly with DoubleClick and other early ad tech pioneers. The company went public and grew rapidly through acquisitions, including the merger with Real Media in 2001 to form 24/7 Real Media. 24/7 Real Media continued to operate as a significant player in the digital advertising space, offering ad serving platforms, publisher network services, and data-driven targeting capabilities. The company served major brands and publishers globally, with a particularly strong presence in international markets. Its Open AdStream ad serving platform became a widely adopted solution among publishers seeking to manage and monetize their digital inventory. In 2007, WPP Group, the global advertising and communications conglomerate, acquired 24/7 Real Media for approximately $649 million. Following the acquisition, the company's technology and operations were integrated into WPP's broader digital advertising portfolio, with the Open AdStream platform continuing to serve clients under WPP ownership. The brand and its technology assets were eventually absorbed into Xaxis and other WPP digital units, marking the end of 24/7 Real Media as a standalone brand.
