Culture Hive brings Cultural Relevance scoring to programmatic buying through Magnite ClearLine. Culture Hive brings its Cultural Relevance Score to Magnite ClearLine, helping advertisers target culturally relevant audiences and media at scale. "We know what captures attention: content that reflects people's identities. The Cultural Relevance Score makes that measurable, and Magnite brings it to programmatic at scale."" - Joe Ligé, CEO & Founder, Culture Hive NEW YORK, NY, UNITED STATES, July 22, 2026 /EINPresswire.com/ - Today, Culture Hive Media Group announced the integration of its proprietary Cultural Relevance Score (CRS(TM) into Magnite's ClearLine platform, giving advertisers a measurable way to identify and activate against culturally relevant audiences and media environments. For decades, advertisers have relied on demographics as a proxy for audience understanding because culture was difficult to measure at scale. CRS changes that by giving advertisers a measurable signal for identifying culturally relevant audiences and media environments. Through curated programmatic supply, advertisers can use CRS to evaluate content, audiences and media environments against cultural communities, affinities and moments, helping identify where cultural resonance exists and activate against it at scale. "We already know what captures people's attention: content and communities that reflect how they see themselves. The Cultural Relevance Score turns that intuition into a measurable signal. Through Magnite advertisers can now activate against that signal at scale," said Joe Ligé, CEO and Founder, Culture Hive. Today, a brand looking to reach runners often relies on demographic proxies and hopes the campaign finds the right audience. With CRS in ClearLine, that same brand can target the actual environments where running culture lives, from training content to gear communities to race-day moments, and reach an audience defined by what they care about, not what census bracket they fall into. Through Magnite ClearLine, Culture Hive will curate inventory packages informed by CRS, helping advertisers identify culturally relevant media environments with the transparency and control expected from premium programmatic buying. "Advertisers increasingly want to go beyond audience reach; they want context, relevance and confidence in where their campaigns appear," said Mike Dupree, Senior Vice President, Demand at Magnite. "ClearLine helps curator partners bring differentiated intelligence into programmatic transactions. By bringing Culture Hive's Cultural Relevance Score into ClearLine, advertisers gain a new way to discover and activate against culturally relevant supply while publishers benefit from increased demand for premium inventory." For publishers, the integration creates a new way to surface and monetize the cultural relevance of their inventory. For advertisers, it provides a scalable path beyond demographic proxies and toward media investments informed by culture. "Publishers have always known their inventory carries cultural value that demographic targeting can't capture," said Kirk McDonald, CEO of Sundial Media & Technology Group. "CRS helps make that value visible, giving advertisers a better way to discover publishers that genuinely resonate with the audiences they want to reach." About Culture Hive Culture Hive Media Group's mission is to shift the advertising industry from demographic targeting to culture-first activation. Through its proprietary cultural intelligence technology and Cultural Relevance Score (CRS(TM), the company helps brands better understand and connect with audiences based on shared values, identity, and community - turning cultural fit into a measurable advantage.

Stagwell cleans path to media buys. Removing traditional ad-tech middlemen and build its own private platform will allow Stagwell to determine how ad space is selected and bundled for its clients, rather than relying on automated third-party ad exchanges. The holding company is preparing to launch "Stagwell Curate," an AI marketplace that centralizes curated media inventory including connected TV, online video, display, and audio ads from publishers and ad-tech partners. "We've brought together our preferred publisher relationships, private marketplace deals and supply partnerships into one scalable platform," Matt Adams, global CEO of Stagwell Media Platform, told MediaPost in an email. "It allows brands to move beyond buying what's available and instead access inventory that has been deliberately selected for quality and performance." Adams believes the biggest advantage for advertisers from Stagwell Curate - part of the Stagwell Media Platform - is better access to quality inventory and greater control over where media budgets are spent. The Media Machine buying agents will connect directly to Stagwell Curate, giving them instant access to to preferred publisher relationships, pre-negotiated private marketplace deals and exclusive pricing when sourcing inventory. Inventory through the platform is continuously evaluated using log-level data and supply-quality models powered by The Trade Desk's Sincera. Adams described the key to the platform as the ability to curate ad supply closer to publishers to reveal premium ad-buying opportunities traditional bid optimization can miss. It streamlines the programmatic supply chain to eliminate redundant intermediaries and fraudulent practices. Ad agencies traditionally buy inventory through demand-side platforms (DSPs) and trust that the supply path is clean. This means buying digital ad space with the fewest middleman fees, zero fraud, and visibility into where the money goes. Clients including Nike, Lenovo, Target, Starbucks and Bud Light - although it is not determined whether the brand uses Curate - could use the new platform as Stagwell clients. The Interactive Advertising Bureau (IAB) estimates total U.S. advertising spend across all media is projected to grow 9.5% year-over-year in 2026. Released in April and based on projections, the total U.S. ad spend across all channels could reach approximately $500.98 billion in 2026. This technology moves curation in-house. It creates an agency-owned layer above the DSP to filter and control eligible inventory before a bid gets placed Data and intelligence, along with quality standards and performance signals, are applied upstream, meaning closer to the original source, to evaluate inventory before it reaches the bid. Through direct integration with partners such as FreeWheel and Magnite, and connections to The Media Machine's AI buying agents, Stagwell can curate that supply closer to the source. Theoretically, each media buying decision is informed by more data, greater transparency and a more complete view of available performance opportunities.
