One by AOL

One by AOL was a digital advertising technology brand focused primarily on display advertising for mobile devices. It was created in October 2015 after AOL completed its acquisition of Millennial Media, a mobile advertising company founded in 2006 by Paul Palmieri and Chris Brandenburg. The rebranding placed Millennial Media's mobile advertising capabilities within AOL's broader advertising technology portfolio. Before becoming One by AOL, Millennial Media developed a business around helping advertisers reach audiences on smartphones and other mobile devices. Its activities included mobile display advertising, audience targeting, campaign delivery, and advertising technology services for publishers and marketers. The company expanded through acquisitions, purchasing TapMetrics in 2010, Condaptive in 2011, Jumptap in 2013, and Nexage in 2014. These transactions broadened its capabilities in mobile analytics, data, programmatic advertising, and mobile ad exchanges. Millennial Media also pursued an independent public-market strategy. It filed for an initial public offering with the U.S. Securities and Exchange Commission in January 2012 and became publicly listed in March of that year. The company underwent a leadership transition in January 2014, when co-founder Paul Palmieri stepped down and Michael Barrett became chief executive. AOL agreed to purchase Millennial Media for approximately $238 million in September 2015, and the transaction closed on October 23, 2015. AOL then changed the business's name to ONE by AOL, integrating its mobile advertising assets into AOL's wider advertising platform. The brand was part of AOL's attempt to offer advertisers a more unified set of tools spanning different digital formats and devices. One by AOL did not remain a standalone proposition indefinitely. After Verizon combined AOL and Yahoo-related assets under the Oath organization, Oath announced in September 2018 that BrightRoll, One by AOL, and Yahoo Gemini would be consolidated into a single advertising offering called Oath Ad Platforms. This consolidation effectively ended One by AOL as a separate brand. Its history is therefore best understood as the final brand phase of Millennial Media rather than as a long-lived independent consumer-facing brand.

One by AOL originated in Millennial Media, which was founded in May 2006 by Paul Palmieri and Chris Brandenburg. The original company concentrated on mobile advertising, a market that was expanding as smartphones and mobile applications became important channels for publishers and marketers. Its business served advertisers seeking mobile reach as well as publishers looking to monetize mobile audiences through display advertising. Millennial Media expanded its capabilities through a series of acquisitions. TapMetrics was acquired in 2010, followed by Condaptive in 2011. In 2013, the company acquired Jumptap, strengthening its mobile advertising and targeting capabilities. Nexage followed in 2014, adding further exposure to programmatic mobile advertising and exchange infrastructure. These acquisitions reflected the company's effort to assemble a broader technology stack rather than rely solely on direct mobile ad sales. The company pursued substantial outside financing during its early growth period and later entered the public markets. It filed for an initial public offering with the U.S. Securities and Exchange Commission in January 2012 and was first listed in March 2012. In January 2014, co-founder Paul Palmieri left the chief executive role and was replaced by Michael Barrett. AOL announced in September 2015 that it would acquire Millennial Media for approximately $238 million. The transaction closed on October 23, 2015. AOL subsequently renamed the business One by AOL, aligning it with AOL's broader portfolio of advertising and publishing technologies. Under the new identity, the business continued to represent mobile advertising capabilities, including display advertising, audience targeting, programmatic tools, and publisher-oriented technology. The brand's independent life was limited by broader corporate consolidation. AOL and Yahoo assets were later organized under Oath following Verizon's integration of the businesses. On September 10, 2018, Oath announced that BrightRoll, One by AOL, and Yahoo Gemini would be consolidated into a unified advertising proposition named Oath Ad Platforms. This decision brought the One by AOL brand to an end as a distinct advertising platform. The brand therefore represents a transitional stage in the evolution from Millennial Media's standalone mobile advertising company to a consolidated advertising technology operation within AOL and then Oath.
