HBO Max

Premium CTV advertising platform and streaming service under Warner Bros. Discovery, competing in the top tier of ad-supported streaming alongside Peacock, Hulu, and Paramount+

HBO Max is Warner Bros. Discovery's flagship streaming platform, carrying one of the most storied brand names in premium entertainment. Launched in May 2020, the service underwent a significant rebrand to 'Max' in May 2023 when it merged with Discovery+ content, before reverting to the HBO Max name in July 2025. The platform offers a vast library of HBO originals, Warner Bros. films, DC content, sports, and discovery programming, competing directly with Netflix, Disney+, and Peacock in the premium streaming wars. From an AdTech perspective, HBO Max is a significant connected TV (CTV) advertising surface. The ad-supported tier launched in June 2021 and has grown substantially, attracting brand advertisers seeking premium, brand-safe inventory alongside prestige content. Warner Bros. Discovery sells advertising through its own sales organization as well as programmatically via partnerships with major DSPs and SSPs, offering targeting capabilities including first-party data, contextual targeting, and audience segments derived from its broad media portfolio. As a subsidiary of Warner Bros. Discovery (NASDAQ: WBD), HBO Max benefits from the parent company's extensive advertising sales infrastructure, cross-portfolio bundling opportunities, and data assets spanning linear TV, streaming, and digital properties. The platform competes aggressively for upfront and scatter market ad dollars, positioning its premium content environment and engaged subscriber base as key differentiators against both pure-play streamers and traditional TV networks.
