The Future of OOH Publishing: Automation, Data, and Scalable Growth

Why OOH is Entering a New Golden Era

Out-of-home (OOH) advertising has long been the channel for scale and spectacle, from Times Square billboards to digital transit screens. Yet in 2025, OOH is being redefined by automation, data-driven targeting, and omnichannel convergence.

For decision-makers at publishers, media companies, and advertisers, the opportunity is profound. According to a recent market analysis, the global out-of-home advertising market was valued at approximately US $50.1 billion in 2024, and is forecast to grow at a CAGR of 5.5% from 2026 to 2033, reaching around US $78.5 billion by 2033. But growth won’t come from screens alone. The future belongs to those who can connect automation, first-party data, and scalable systems that transform OOH from static placements into measurable, performance-driven media.

The Opportunity: OOH in a Data-First Advertising Landscape

OOH is no longer a standalone channel. It sits at the intersection of commerce, mobility, and digital media convergence.

• Digital Transformation: Programmatic DOOH is rapidly scaling. Programmatic trading is expected to account for nearly 90% of global digital display ad spending in 2025, reinforcing how automation is extending not just within DOOH but also into CTV and addressable linear TV.
• Retail Media Convergence: In-store screens, like Hy-Vee’s 10,000 new retail displays, illustrate how OOH is merging with retail media to influence shoppers at the point of purchase.
• Cross-Channel Planning: Agencies now treat OOH as part of omnichannel campaign management. A CPG ad can start on a bus shelter, extend into CTV, and finish with a shoppable QR code linking directly to a retailer’s app.

For advertisers, this convergence makes OOH a full-funnel channel: delivering brand awareness while increasingly tying exposure to measurable actions.

The Challenges: Fragmentation and Misconceptions

Despite momentum, OOH’s scaling faces three main hurdles:

Fragmented Infrastructure

Each OOH network, transit authorities, retail chains, and private screen owners often operate as a silo. Advertisers must negotiate multiple systems with limited standardization. This echoes the fragmentation seen in retail media networks (RMNs), where 200+ networks globally make unified buying difficult.

Measurement & Attribution Gaps

OOH has historically struggled with proving ROI. While mobile data and geolocation analytics now help track “exposure-to-action,” advertisers still cite measurement inconsistency as a barrier to larger OOH allocations.

Perception Lag

Some still see OOH as “traditional” media, static billboards with limited targeting. Yet the reality is a data-rich, digital-first channel capable of automation and personalization. As one IAB Europe analysis notes, it’s a mistake to view OOH in isolation rather than as part of the wider converged media ecosystem.

Strategic Solutions: Automation, Data, and Convergence

Automation via Programmatic DOOH

The rise of programmatic OOH platforms is enabling advertisers to buy screens with the same efficiency as digital display. ExchangeWire predicts programmatic DOOH will become the dominant model in the UK by 2025. This shift allows:

• Real-time bidding for outdoor inventory.
• Automated targeting by weather, time, or mobility patterns.
• Reduced manual sales overhead for publishers.

Platforms like ADvendio, built on Salesforce, are uniquely positioned to integrate OOH alongside retail media, digital, and CTV in one workflow, streamlining campaign execution.

Data-Driven Targeting

DOOH networks increasingly link with mobile location data, retail data clean rooms, and contextual signals to target audiences precisely. For example, a fitness brand can trigger a campaign near gyms, then retarget exposed users on mobile.

Recent industry surveys show 47% of publishers cite first-party audience activation as their top strategy for post-cookie monetization. OOH can play a central role in these data alliances.

Omnichannel Integration

Forward-looking publishers are collapsing silos to sell cross-platform packages: CTV + DOOH + retail media + digital.

Case in point: Home Depot’s Orange Apron Media integrated in-store digital screens, e-commerce placements, and search into one ad portal, allowing suppliers to run campaigns across touchpoints with a single interface.

Case Studies: How OOH is Scaling with Data and Automation

• Retail Media Meets OOH: The Trade Desk’s partnership with Grocery TV connects in-store retail screens to programmatic demand, enabling CPG brands to target shoppers in real time.
• Connected Commuter Journeys: In Europe, transit authorities are using programmatic DOOH to adjust campaigns dynamically, switching ads based on time of day, train delays, or weather conditions.
• Self-Serve Ad Platforms: Inspired by retail media, publishers are launching DIY tools for OOH. Small businesses can now book a digital bus stop ad as easily as a Facebook campaign, democratizing access.

The Road Ahead: Key Takeaways for Decision-Makers

• OOH is becoming digital-first: By 2026, DOOH will account for half of all OOH revenue, driven by automation and programmatic trading (PwC, WARC).
• Measurement is the unlock: Advertisers demand consistent attribution. Leaders will embrace clean rooms, mobile integrations, and omnichannel reporting.
• Omnichannel is non-negotiable: The most valuable OOH networks will not stand alone but integrate seamlessly with retail, CTV, and digital campaigns.
• Self-serve and scalability are essential: As seen in retail media, self-service portals open OOH to mid- and long-tail advertisers, expanding demand at scale.

For publishers and advertisers alike, the future of OOH lies in automation and data-driven integration. Those who embrace programmatic systems, build first-party data strategies, and converge OOH into omnichannel offerings will capture outsized growth.

From Static to Scalable

OOH is no longer about big signs; it’s about big systems. As retail media, CTV, and digital converge, OOH has the chance to position itself not as “traditional media,” but as the most public, data-enriched, and scalable channel in the mix.

Decision-makers should act now to:

1. Invest in automation platforms to scale efficiently.
2. Build alliances that link OOH to first-party and retail media data.
3. Reframe OOH as a measurable, performance-driven piece of the omnichannel ecosystem.

For companies ready to unify workflows, platforms like ADvendio can offer a single source of truth across OOH, retail media, digital, and CTV, positioning them for growth in a converging, automated future.
