Cathy Oh
Chief Marketing Officer, Samsung Ads & Services at samsung ads
Cathy Oh is the Chief Marketing Officer of Samsung Ads & Services, the global advertising arm of Samsung Electronics, where she has been one of the original leadership voices since the unit's earliest days. Recognized in 2024 by Ad Age as a Leading Women honoree and by Chief Marketer as a People of the Year — CMOs of the Year, she is the named voice on Samsung's CTV-OS, ad-stack, and identity story across NewFronts, CES, and Cannes Lions stages.
Cathy Oh is the named voice for Samsung Ads’ CTV-OS, identity, and ad-stack story across the major industry stages — CES, the NewFronts, Advertising Week New York — and she has been one of the original leadership executives in the unit since its founding. The career arc is structurally relevant: WebMD and NBCUniversal early, then Apple’s iAd Global Brands & Agencies leadership, then a founding-team executive seat at Samsung Ads as the unit grew from a handful of people to an international organization with more than 500 employees.
The recognition cluster in 2024–2025 is the public marker of her current standing. Ad Age named her to the Leading Women 2024 cohort with the headline framing of her ‘second act at Samsung’; Chief Marketer named her one of its 2024 CMOs of the Year and a 2025 Top Women in Marketing honoree; She Runs It honored her as a 2024 Changing the Game recipient. The pattern reads as the trade press marking the turn at Samsung Ads from CTV-OS-as-data-source to CTV-OS-as-platform — and Oh as the public face of how Samsung tells that story.
The recent Samsung Ads anchor moments to track: the 2026 NewFront introducing Performance TV (Samsung positioned as the #1 TV brand leading in CTV performance, with interactive formats delivering 17x higher engagement than the industry average), CES 2026’s flagship Samsung Ads presence, and the Advertising Week New York 2025 program. When our coverage hits Samsung’s identity-and-attention story, Oh is the named voice we cite.
