Scott Greenstein

Scott Greenstein is best known as the long-tenured President and Chief Content Officer of SiriusXM, where he has been a central architect of the company's content strategy and advertising business since the early 2000s. Under his leadership, SiriusXM built one of the largest audio advertising platforms in the United States, leveraging its subscriber base and first-party data to offer advertisers highly targeted, brand-safe environments across satellite radio, streaming, and podcast channels. His work has been instrumental in positioning SiriusXM — and its Pandora acquisition — as a major force in audio advertising technology and programmatic audio. Greenstein joined SiriusXM in 2002 after a career in entertainment and media, including senior roles at United Artists and Viacom. At SiriusXM, he oversaw the signing of landmark talent deals with Howard Stern, Oprah Winfrey, and dozens of other major names, while simultaneously building out the company's ad-supported tiers and monetization infrastructure. The 2019 acquisition of Pandora under SiriusXM's parent Liberty Media significantly expanded the company's addressable advertising market, and Greenstein has been a key voice in integrating those assets into a unified audio advertising offering. In the AdTech context, Greenstein represents the operator archetype — a senior executive who has driven the commercialization of audio inventory at scale, embraced programmatic channels, and championed first-party data strategies as cookies have declined. His influence spans content acquisition, advertiser relationships, and the broader narrative around audio as a premium, measurable advertising medium.
