Adap.tv

One of the first and most prominent independent programmatic video advertising platforms, operating as both a DSP and SSP before being acquired and absorbed by AOL

Adap.tv was a leading video advertising technology company that built one of the earliest and most sophisticated programmatic platforms for buying and selling digital video advertising inventory. Founded in 2007 and headquartered in San Mateo, California, the company developed a unified marketplace that connected advertisers, agencies, and publishers through real-time bidding and automated trading of video ad inventory across desktop, mobile, and connected TV environments. Its platform enabled both buy-side and sell-side participants to transact programmatically at scale, making it a rare dual-sided solution in the emerging video ad tech ecosystem. At its peak, Adap.tv was processing billions of video ad transactions and had established itself as a critical infrastructure layer for the digital video advertising industry. The platform offered a demand-side platform (DSP) for buyers, a supply-side platform (SSP) for publishers, and a video ad server, giving it a comprehensive footprint across the programmatic video stack. This breadth, combined with its data capabilities and real-time decisioning technology, made it one of the most strategically valuable independent video ad tech companies of its era. In August 2013, AOL acquired Adap.tv for approximately $405 million, one of the largest AdTech acquisitions of that period. The technology and team were integrated into AOL's advertising division, and the Adap.tv brand was gradually subsumed — first into the 'One by AOL' platform suite around 2015, then into Oath Ad Platforms following Verizon's acquisition of AOL and Yahoo in 2017–2018, and ultimately into what became the Yahoo DSP. The Adap.tv brand was fully retired, but its technology and programmatic video capabilities formed a foundational layer of the ad platforms that followed it.
