Smart-City Investments Driving Programmatic DOOH Uptake in Asia-Pacific

Municipal authorities in Singapore, Hong Kong, and Vietnam are treating digital kiosks and bus shelters as dual-use assets that deliver civic information and generate advertising revenue. Singapore’s GovTech integrated real-time transit data with 1,200 metro screens, allowing inventory to toggle between way-finding and paid messaging depending on passenger flow.^{[1]GovTech Singapore, “Open Digital Platform,” TECH.GOV.SG} Hong Kong’s Smart City Blueprint 2.0 mandates programmatic ad-serving capability for new public installations, streamlining cross-border buys for regional brands.^{[2]Hong Kong Government, “Smart City Blueprint 2.0,” SMARTCITY.GOV.HK} Hanoi’s 2024 master plan earmarked USD 1.2 billion for 5,000 screens in transit hubs by 2028. Long-tenure concessions encourage operators to finance rapid digitization, compressing payback periods and attracting private equity.

5G-Enabled Real-Time Content Delivery Boosting Highway Screens in North America

Nationwide 5G now covers 87% of the U.S. population, enabling sub-100-millisecond latency that allows billboards to swap creative based on traffic or weather triggers.^[3]FCC.GOV Mobile carriers have installed more than 150,000 5G cell sites, many along highway corridors, reducing backhaul costs for operators. Advertisers reward the flexibility with 15-20% higher CPMs compared with 4G-connected inventory. Edge-compute nodes preload multiple creatives, ensuring seamless playback even when demand-side platforms bid in real time.

Retail Media Networks, Roll-Out Fueling In-Store DOOH Adoption in Europe

European grocers are installing large screen grids that tie impression delivery to loyalty-card data. Tesco already manages over 6,000 screens, delivering personalized offers that refresh every 30 minutes. Carrefour’s retail media unit booked EUR 150 million (USD 169 million) in 2024, with in-store DOOH contributing 35% of that figure. IAB Europe projects tripled spend on retail media between 2024 and 2027, citing closed-loop attribution as the main draw. Regulatory demands for transparency under the Digital Services Act further elevate first-party data, encouraging deeper investment in store networks.

AI-Based Audience Measurement Elevating Advertiser ROI in Transit Hubs

Computer-vision sensors capture age, gender, and dwell-time metrics that flow directly into programmatic auctions. Clear Channel Outdoor’s system in 47 airports adjusts CPMs in milliseconds based on passenger mix. IAB standards now require third-party audits of detection accuracy to maintain buyer confidence. Early studies indicate 22% higher brand-lift scores for AI-verified campaigns compared with static placements. Transit authorities are leasing anonymized footfall data, creating a new revenue stream and tightening the link between urban management and commercial media.

Municipal Energy Caps Restricting Screen Brightness Hours Across EU Urban Cores

EU directives require cities to cut public-sector energy use by 1.9% annually, prompting rules that force screens to dim or shut off overnight. Paris mandates shutdown from 1 AM to 6 AM, reducing available inventory by 20% and stripping EUR 45 million (USD 51 million) in yearly revenue from operators.^{[4]City of Paris, “Digital Signage Ordinance 2024,” PARIS.FR} Amsterdam caps brightness at 300 nits in evenings, lowering visibility and pushing advertisers to pricier daytime slots. German municipalities have begun denying permits for new commercial screens, citing environmental concerns. These localized rules fracture the European network, undercutting the scale economies on which programmatic efficiency depends.

Fragmented Measurement Standards Hindering Cross-Network Programmatic Buys in the U.S.

Seventeen distinct audience methodologies complicate impression reconciliation, inflating transaction costs and forcing agencies back to manual insertion orders. Proprietary models create data silos; 62% of U.S. operators rely on non-interoperable systems. Clear Channel Outdoor reported a 14% shortfall in 2024 programmatic growth relative to direct sales, citing impression-delivery disputes. Until cross-network standards emerge, programmatic liquidity will lag, keeping some budgets on hold.

Segment Analysis

By Format: Street Furniture Gains from Municipal Smart-City Contracts

Street furniture revenue is expected to climb at an 11.20% CAGR through 2031, outpacing all other formats. Concession renewals in London, Paris, and Singapore require operators to install thousands of digital kiosks that provide public Wi-Fi and transit data alongside advertising. This model secures long-term rights while shifting capital costs to private partners, increasing economic resilience against advertising cyclicality. Digital billboards remain dominant in sheer revenue because of 38% share in 2025, but zoning limits hinder fresh deployments near residential areas. Transit displays grow steadily inside metro and airport environments where captive audiences welcome longer dwell-time creative. Venue screens inside gyms, cinemas, and campuses broaden advertiser reach but remain fragmented due to varied ownership structures. As municipalities lean on private funding, the dual public-service and advertising role of street furniture further cements its growth trajectory.

Operators increasingly package street furniture within broader mobility ecosystems, using anonymized sensor data to coordinate public alerts and commercial content. This infrastructure-as-a-service positioning insulates contracts from backlash against pure commercial clutter. In Asia-Pacific, street furniture also serves as a springboard for facial-recognition ticketing pilots, raising privacy debates but enhancing measurement sophistication. The cumulative effect is a format that balances civic utility with commercial upside, making it the centerpiece of many smart-city master plans.

By Screen Technology: LED Dominance Challenged by Projection Innovations

LED held 61% of 2025 revenue thanks to high brightness and falling panel costs, but projection and other technologies are pacing at 10.67% CAGR. Transparent LED tiles allow retailers to overlay digital content on window displays, merging out-of-store reach with in-store engagement. Laser projection and holography create immersive activations in airports and flagship stores without the structural load of heavy panels. Energy-efficient e-paper pilots in Germany consume 99% less power, appealing in cities grappling with energy caps. LCD usage is shrinking outdoors because of glare and power draw, but it retains a niche for menu boards and lobbies where ambient light is controlled.

Advertisers favor novel projection formats for experiential campaigns that generate social-media buzz. PwC research shows these activations deliver more than triple the earned-media value of conventional digital spots. Operators, however, must weigh creative differentiation against maintenance complexity. Diverse hardware fleets demand specialized service teams, increasing overhead. Yet as regulatory pressure intensifies around energy and light pollution, lower-power alternatives could gain share faster than current forecasts suggest.

By Location: Indoor Installations Capture Retail Media Budgets

Indoor networks are predicted to rise at 10.86% CAGR as supermarkets, pharmacies, and clinics monetize dwell time near the point of purchase. Screens tie into point-of-sale systems, allowing real-time creative triggered by stock levels and loyalty data. Walgreens generated USD 250 million from its in-store network in 2024, with screens delivering 28% higher conversion than online display, underlining the format’s performance credentials. Outdoor still commands 72% of 2025 spending, thanks to its unmatched reach along arterial roads and transit corridors. However, increasing community complaints about visual pollution and tougher permitting procedures restrict new outdoor capacity.

Indoor environments permit higher resolution, interactive touchpoints, and controlled lighting, making them ideal for AR overlays and QR-code-driven promotions. Healthcare waiting rooms leverage screens for condition-specific content that aligns with patient-engagement mandates, underpinning the 11.06% CAGR in the healthcare vertical. Retailers are integrating advertising revenue into category management decisions, setting CPM floors linked to basket-margin data. This commerce-adjacent integration strengthens the case for on-premise screens, pushing advertisers to allocate higher shares of digital spend inside the store.

By End-User Vertical: Healthcare Leads Growth on Patient-Engagement Mandates

Healthcare and pharmaceuticals is on track for an 11.06% CAGR to 2031, driven by screens in pharmacies, clinics, and hospital corridors. Deloitte research links digital patient engagement to lower no-show rates and improved medication adherence, providing a clinical ROI beyond ad revenue. CVS Health operates more than 9,000 pharmacy screens that combine branded drug promotions with dosage-reminder content, achieving 34% higher recall than brochure racks. Retail conditions still dominate the revenue pool with 27% of 2025 share as grocers push own-label items through in-aisle screens. Financial services and automotive brands pursue affluent commuters in transit hubs, while telecom firms promote bundled digital services during device upgrade cycles. Government bodies use inventory for emergency alerts, reinforcing the public-service narrative that helps justify municipal concessions.

Regulation is moving in step, with U.S. authorities clarifying that anonymized targeting on clinic screens can comply with HIPAA, provided opt-out mechanisms are visible. This guidance unlocks pharmaceutical budgets that were previously cautious about waiting-room media. As telehealth platforms expand, cross-screen retargeting between clinic visits and mobile apps will likely create fresh demand for authenticated audiences within the healthcare ecosystem.

Geography Analysis

North America held 34.50% of value in 2025. Mature programmatic infrastructure, high CPMs in tier-1 metros, and nearly ubiquitous 5G coverage enable dynamic roadside messaging that rivals mobile display in precision. Canadian growth centers on Toronto, Vancouver, and Montreal, where subway concessions fund transit operations. Mexico’s progress is slower because measurement fragmentation deters global buyers, although mall deployments in Mexico City are gaining traction. Regulatory scrutiny of AI audience tracking and measurement standardization remains a headwind, potentially tempering short-term gains.

Asia-Pacific is projected to register an 11.40% CAGR, the highest worldwide. Smart-city blueprints in Singapore, Hong Kong, and Vietnam embed digital signage into public infrastructure, ensuring reliable public funding streams. China’s tier-1 renovation projects are digitizing vast subway and bus networks, although escalating land-lease fees compress operator margins and stimulate consolidation. Japan’s new programmatic marketplace in Tokyo and Osaka provides real-time bidding, attracting multinational advertisers seeking regional scale. India remains nascent but benefits from rapid urbanization and a broad migration from print to digital placements.

Europe’s trajectory hinges on retail media network expansion and evolving regulatory frameworks. Grocers deploy extensive in-store screens tied to loyalty data that satisfy Digital Services Act requirements for advertising transparency. Energy-consumption limits force outdoor operators to dim screens at night, reducing available impressions and shifting spend to indoor environments. Despite these constraints, metro systems in London, Paris, and Berlin continue to digitize, supported by public-private revenue-sharing models. The Middle East and Africa region accelerates through sovereign megaprojects in United Arab Emirates and Saudi Arabia, where urban master plans allocate thousands of screens as part of tourism and transit hubs. South America remains smaller but is picking up pace in Brazil and Chile, with mall and metro projects seeking to counterbalance macroeconomic volatility.
