MediaPost

MediaPost is an American trade publication covering the advertising, marketing, and media industries, with particular depth on digital advertising strategy, programmatic buying, audience targeting, and media planning. The publication was among the specialist outlets tracking WPP Media's launch of its video Buyer Agent and the Agentic Standards Initiative at Cannes Lions in June 2026, covering a moment of structural change in how advertising inventory is bought across digital and broadcast channels.

Founded in 1999, MediaPost operates a network of newsletters, websites, and industry events serving advertising professionals. Its portfolio includes titles such as Media Daily News, a suite of topic-specific newsletters covering programmatic, mobile, social, and television advertising, and a conference business. The publication is headquartered in New York and circulates primarily within the US advertising ecosystem, though its coverage of major platform and technology announcements gives it reach among media buyers, agency strategists, and publishers internationally. It is independently owned and positions itself as a practitioner-focused outlet rather than a trade commentary title.

Trade publications like MediaPost occupy a specialist function in the media ecosystem: they translate platform announcements, deal structures, and regulatory changes into the practical language of practitioners. As the advertising industry shifts towards AI-driven autonomous buying, MediaPost's longstanding editorial focus on programmatic and digital advertising positions it as a natural chronicler of the agentic transition, whose audience of media directors and trading-desk operators are the same professionals who must decide whether and how quickly to adopt these systems.
