South Korea OOH And DOOH Market Analysis by Mordor Intelligence
The South Korea OOH and DOOH market size was valued at USD 711.32 million in 2025 and estimated to grow from USD 759.89 million in 2026 to reach USD 926.17 million by 2031, at a CAGR of 4.04% during the forecast period (2026-2031). The South Korean OOH and DOOH market is supported by two parallel shifts: the wider digitization of public media assets and a policy backdrop that has made large-format digital screen deployment easier in dense commercial areas. The full operation of the second-phase free display zones in Gwanghwamun, Myeongdong, and Haeundae Beach by late 2025, along with the review of a third zone in Dongdaemun, shows that regulatory easing is still shaping supply growth rather than fading after an initial rollout. The South Korea OOH and DOOH market is also moving toward more targeted buying as retail media networks, mobility-linked inventory, and programmatic tools connect screens that were previously managed in isolation. At the same time, the push toward audience verification is reducing a long-standing credibility gap with mobile and video channels, even though fragmented ownership and crowded ad loops on premium digital landmarks still limit pricing power for some advertisers. The 2026-2028 tender cycle for bus shelters and exterior bus advertising in Seoul is likely to be an important test of whether the South Korea OOH and DOOH market can move to a stronger long-term growth path.

Expansion of Free Display Zones and Landmark Digital Screens
The South Korean OOH and DOOH market has benefited from direct support from free display zones, which reduce approval friction and attract large-format installations into the country’s busiest commercial corridors. By September 2025, the second-phase zones in Gwanghwamun, Myeongdong, and Haeundae Beach were fully operational, which expanded the pool of permitted premium digital inventory in both Seoul and Busan. The regulatory push did not stop at national designation, as Seoul’s March 2025 ordinance amendment also expanded the scope for digital window advertising and related pilot formats within the city. This combination has made the South Korean OOH and DOOH market more attractive for large branded screens that want both landmark visibility and a clearer operating path. At the same time, higher screen density in those districts has not diminished demand for static formats, because long ad loops on premium digital sites reduce exclusivity for luxury brands that still value uninterrupted presence.
Rising Programmatic DOOH Adoption Across Mobility and Transit Assets
The South Korea OOH and DOOH market is moving away from isolated screen buying as operators connect mobility, transit, and place-based assets into single buying systems. In November 2025, Kakao Mobility signed agreements with KT Nasmedia, CJ Mezzomedia, and Incross to build an operating structure for automated real-time bidding across a unified pool of nearly 40,000 screens.[1]Kim Sung-hyun, “KT Launches ‘Retail Media Network’ With GS Retail,” Korea Post, koreapost.co.kr Because that inventory spans taxi rear-seat displays, KTX station panoramas, bus shelters, convenience stores, and campus screens, advertisers can now plan to reach across several daily travel touchpoints instead of booking each format separately. Incross linked its Dawin video platform with Kakao Mobility’s DOOH inventory to connect physical exposure more directly with mobile outcomes, which speaks to a core weakness that had limited DOOH budget shifts in the South Korean OOH and DOOH market. A second access layer is also forming through AI-led self-serve tools such as Naver’s ADVoost Screen, which broadens entry for smaller advertisers while larger buyers continue to use managed platforms. This makes the South Korea OOH and DOOH market more flexible for both national brand campaigns and local campaigns that need faster planning and lower operational friction.
Retail Media Network Expansion across Convenience and Grocery Touchpoints
The South Korea OOH and DOOH market is being reshaped by retail media because convenience stores, grocery formats, and nearby community venues now act as high-frequency media nodes. KT entered this space through its Baro Ad platform in more than 1,000 GS25 stores in the Seoul metropolitan area, linking telecom data with store-level advertising delivery. At the same time, GS Retail expanded Top View and GSTV signage across more than 5,000 GS25 and GS The Fresh outlets, and some stores added AI demographic cameras that connect campaign serving to in-store traffic patterns. Focusmedia Korea also expanded access to its 60,000-elevator TV network in the Seoul metropolitan area, giving local commercial users a dense, neighborhood-level screen footprint beyond transit and landmark sites. E-mart’s 2026 launch of an integrated online-offline retail media platform adds another large-scale channel into the South Korea OOH and DOOH market, built around a retail estate with nationwide physical presence and strong app traffic. As these networks expand, the South Korea OOH and DOOH market gains better closed-loop reporting because impressions can be checked against same-location purchase behavior rather than treated as broad awareness only.
Mobility Data-Based Audience Planning and Omnichannel Attribution
The South Korea OOH and DOOH market is improving its measurement base as operators move from simple traffic counting toward audience quality and attention metrics. In December 2025, 35 organizations agreed on a three-stage framework that measures traffic, exposed audience, and attentive audience, using Vision AI and mobile network data from SK Telecom and KT across major test sites. Korea also moved closer to international practice when the Korea Out of Home Association published the Korean version of the World Out of Home Organization audience measurement guidelines in December 2024. This direction matters because the South Korea OOH and DOOH market competes for budgets against channels that already offer better attribution, and comparable standards make cross-media planning easier for multinational buyers. Live synchronized campaigns across large national screen pools have also shown how measured reach can be paired with social amplification, as entertainment campaigns for artists such as Le Sserafim and Stray Kids ran simultaneously across 40,000 screens. The result is a South Korea OOH and DOOH market where audience planning is becoming more evidence-based, even if full cross-network consistency has not yet been achieved.
Restraints Impact Analysis
| Restraint | (~) % Impact on CAGR Forecast | Geographic Relevance | Impact Timeline |
|---|---|---|---|
| Fragmented ownership and incomplete cross-network measurement standards | -0.8% | National, with sharper effects in non-Seoul secondary cities | Short term (≤ 2 years) |
| Advertiser budget scrutiny versus easier-to-prove digital performance channels | -0.6% | National, especially among mid-market advertisers | Medium term (2-4 years) |
| Screen supply inflation and lower sell-through in newly digitized inventory | -0.4% | Newly digitized transit and bus shelter inventory outside Seoul CBD | Medium term (2-4 years) |
| Long ad loops reducing share of voice on premium landmark screens | -0.3% | Gwanghwamun, Myeongdong, COEX, and other high-density free display zones | Short term (≤ 2 years) |

Fragmented Ownership and Incomplete Cross-Network Measurement Standards
The South Korea OOH and DOOH market still operates with a fragmented ownership base that includes transit authorities, municipalities, landlords, and many independent operators. The December 2025 standardization agreement was an important step, but it included 35 organizations rather than the whole operator base, so the new framework is not yet a universal trading currency. This creates practical friction because national advertisers still need manual planning across formats that sit on different data systems and use different reporting logic. The issue is sharper outside Seoul, where newer operators are only beginning to build digital inventory and measurement routines, as seen in Daejeon’s first station media wall rollout in 2025. Until a broader GIS-based and cross-network measurement layer becomes commercially routine, the South Korea OOH and DOOH market will continue to lose some budget to channels that offer cleaner reach, frequency, and duplication reporting. This restraint does not stop growth, but it slows premium pricing and weakens comparability across national campaigns.
Advertiser Budget Scrutiny Versus Easier-to-Prove Digital Performance Channels
The South Korea OOH and DOOH market also faces pressure from marketers who must justify spending against channels with clearer attribution models. Even when mobile social and search become more crowded, OOH still competes with connected TV and digital video for the same upper-funnel and brand-building budgets. The strongest advertisers can still spend heavily: the 5 major Korean banks invested KRW 813.6 billion (USD 541 million) in advertising during 2025, with transit DOOH and large digital formats used for celebrity-led campaigns. The harder challenge sits in the mid-market, where buyers want visible cost-per-acquisition proof and may shift marginal spend to channels with stronger conversion reporting. Programmatic links between DOOH impressions, app downloads, and in-store actions are improving that case inside the South Korea OOH and DOOH market, but adoption requires time, platform trust, and advertiser training. As long as proof remains uneven across networks, budget scrutiny will continue to cap part of the upside for the South Korea OOH and DOOH market.
Segment Analysis
By Service Type: Digital OOH Holds the Lead While Static Keeps a Premium Role
Digital OOH accounted for 68.43% of the South Korea OOH and DOOH market in 2025, and digital OOH is forecast to expand at a 5.13% CAGR through 2031. That lead shows the South Korea OOH and DOOH industry has already moved past the point where digital is a niche extension of legacy outdoor media. Even so, static OOH remained relevant in 2025 because luxury brands, public campaigns, and local advertisers still valued guaranteed exclusivity and uninterrupted visibility. This matters most on landmark screens where long ad loops can include many advertisers in one cycle, which reduces the share of voice available to any single brand. In practice, that has preserved a premium role for selected static placements even as the South Korea OOH and DOOH market keeps shifting toward digital delivery.
The digital side is broadening through several layers at once, including large landmark screens, place-based networks, and programmatic buying pipes. Seoul Station’s Platform 111 became a centerpiece for branded campaigns from companies such as Samsung Electronics and Prada, showing how transit-integrated digital displays can serve both audience scale and visual impact. Place-based networks are also growing quietly through elevator TV, offices, apartments, universities, and healthcare venues, with Focusmedia Korea’s 60,000-screen elevator network standing out as a dense reach platform. Programmatic DOOH is still in an early commercial phase in 2026, but the Kakao Mobility ecosystem is pushing the South Korea OOH and DOOH market toward more automated planning and reporting. At the same time, the Basic AI Act, enacted in January 2025 and effective from January 2026, adds disclosure and transparency requirements that will shape how AI-generated DOOH creative tools are deployed at scale.
By Application: Billboards Remain Core While Transportation Gains Speed
Billboard inventory held 33.28% of the South Korea OOH and DOOH market size in 2025, which confirms that large-format outdoor screens and display surfaces remain the base layer for mass visibility. The strength of billboards reflects continued investment in landmark exterior media across commercial districts, highways, and designated free display zones. Seoul’s 37-inch LCD rollout across 5,000 city buses and the expansion of panoramic KTX station displays show how transit supply is giving the South Korea OOH and DOOH market a larger and more measurable moving audience base.[2]Jeong Dong-seon, “Seoul City Bus ‘37-inch Wide LCD’ Digital Media Platform Service,” Seoul STV News, stvnews.kr Gwanghwamun added significant digital capacity in 2025, reinforcing Seoul’s efforts to position the corridor as a regional media landmark rather than merely a domestic advertising district. Transportation inventory is the fastest-growing application, with a 5.63% CAGR projected for 2026-2031, supported by stronger digitization of airports, rail stations, buses, and shelters.
Street furniture is evolving through municipal policy and infrastructure cycles rather than only through advertiser demand. Seoul’s 2025 ordinance revision widened room for digital window displays and pilot formats linked to smart poles and street-level video facilities. Retail and mall screens are also gaining weight as large chains convert store traffic into paid media inventory, with E-mart’s 2026 integrated retail media platform standing out as an important near-term move. Airport and other premium transit locations continue to attract automotive, luxury, and financial advertisers because traveler profiles support premium pricing and stronger brand fit. Other locations, including campuses and auto service centers, are entering addressable buying systems through platform aggregation, which expands the usable footprint of the South Korea OOH and DOOH market beyond classic outdoor sites.
By End-user Industry: Retail Leads Demand While Entertainment and Streaming Grow Faster
Retail and consumer goods represented 48.37% of total end-user demand in 2025, making them the largest spending group in the South Korea OOH and DOOH market. That position reflects both campaign volume and a deeper link between store traffic, first-party data, and digital signage planning. The South Korea OOH and DOOH industry is seeing retailers combine in-store screens, nearby billboards, and mobile retargeting under one reporting logic rather than treating each touchpoint as a separate media buy. GS Retail showed this approach through AI camera-equipped stores and strengthened store-app advertising integration in 2025. Entertainment and media streaming is the fastest-growing end-user segment, with a 5.38% CAGR projected through 2031, supported by album launches, countdowns, release promotions, and esports-linked visibility.
This part of the South Korean OOH and DOOH market is especially active because live, synchronized-screen campaigns can spill into social media without extra media costs. Kakao Mobility’s 40,000-screen synchronized format for artists such as Le Sserafim and Stray Kids shows why entertainment buyers treat DOOH as a native amplification channel rather than just an outdoor awareness tool. Automotive brands are also active, with Innocean Worldwide using landmark locations in Gangnam, Banpo, Yeouido, and Myeongdong for high-visibility vehicle launches. BFSI spending rose sharply as the 5 major Korean banks spent KRW 813.6 billion (USD 541 million), on advertising in 2025, and large-format digital and transit media were important parts of that mix. Healthcare and pharma also remain relevant through pharmacy-linked proximity campaigns and vehicle-based media, while government and public sector demand continues to support informational and civic messaging across transit and municipal infrastructure.
Geography Analysis
The South Korea OOH and DOOH market is concentrated in the Seoul metropolitan area, including Seoul, Incheon, and the Gyeonggi corridor, because this geography combines the country’s highest footfall, strongest advertiser density, and most developed premium screen infrastructure. Gwanghwamun, Myeongdong, and COEX form the country’s highest-value concentration of landmark digital inventory and continue to attract budgets from luxury, automotive, and entertainment advertisers. Seoul Station’s Platform 111 set a new benchmark for transit-led DOOH in the country with a 111-meter continuous LED screen serving more than 100 million annual users across rail, metro, and taxi transfer flows. JCDecaux Korea’s footprint of nearly 5,000 advertising faces across Seoul shows how landmark formats sit alongside bus shelters, transfer centers, and district-level networks rather than replacing them.[3]“About Us,” JCDecaux Korea, jcdecaux.co.krSeoul’s smart city rollout also adds depth to this geography, with more than 1,000 integrated S-Poles extending the city’s digital information and screen infrastructure.
Busan, Daejeon, Daegu, and other secondary cities are becoming the next layer of expansion for the South Korea OOH and DOOH market. Haeundae Beach has already given Busan a tourism-led free display zone that is starting to attract hospitality and entertainment demand. Korea Investment and Securities opened a large digital signage installation in Busan Seomyeon in May 2026, which shows that BFSI brands are now willing to treat secondary cities as valid landmark advertising locations. Daejeon’s first station media wall also showed that demand can build quickly once modern screen supply is introduced, because the site was close to fully booked soon after launch.
The biggest geographic gap in the South Korea OOH and DOOH market is no longer only screen quantity, but the uneven quality of measurement and buying infrastructure between Seoul and the rest of the country. Seoul already has programmatic-connected screens, mobility-data targeting, and AI-supported audience measurement, while many secondary markets are still replacing static public boards with basic digital units. This creates a two-speed operating model where national advertisers often use one planning method for Seoul and another for smaller cities. Platform aggregators such as Kakao Mobility and KT are well placed to reduce that gap as their data systems and content management capabilities spread beyond the capital region.
Competitive Landscape
The South Korea OOH and DOOH market remains fragmented, with competition spread across place-based media owners, transit concession operators, telco-backed platforms, and global outdoor specialists. No single company controls a majority of revenue, even though some operators have built large inventory pools in specific formats or venues. Focusmedia Korea’s 60,000 elevator TVs give it strong reach in residential and office environments, while Kakao Mobility’s network of nearly 40,000 screens under one CMS gives it scale across mobility, transit, and place-based inventory. JCDecaux Korea continues to defend a quality-led position through street furniture and municipal concession experience, supported by an international operating base from its parent group, which reported EUR 3,935.3 million in global revenue in 2024, approximately USD 4,260 million. The programmatic partnership tying Kakao Mobility to KT Nasmedia, CJ Mezzomedia, and Incross shows that scale alone is no longer enough in the South Korean OOH and DOOH market, as interoperability and audience accountability are becoming equally important.
Competitive behavior in 2025 and 2026 points to a clear platform race. Kakao Mobility’s selection as the preferred bidder for CJ Olive Young’s signage across nearly 1,300 stores would deepen its retail media density and widen its reach beyond transit-heavy environments.[4]“제이씨데코 코리아, ‘2026 연등회’ 맞아 종로 이동식 정류소 가동 완료,” Seoul Newspaper, m.seoul.co.kr Its collaboration with d’strict at Seoul Station also shows a parallel strategy built around premium media art, branded storytelling, and multi-screen synchronization rather than only performance-led screen selling. SK Networks’ acquisition of Incross in January 2026 added another strategic move, because it pulled a digital advertising specialist into a larger consumer-facing group that can connect programmatic video, DOOH, and commerce touchpoints. Focusmedia Korea’s 2025 partnerships with 17 general advertising agencies point to a similar need to widen access and improve fill rates for large local screen networks.
The next competitive advantage will likely come from who can make national planning feel simple in a still uneven landscape. Smaller independent operators may keep valuable local inventory, but they are at a disadvantage when advertisers want faster buying, unified reporting, and audience verification across cities. That leaves room for aggregators and concession specialists that can normalize data, package diverse formats, and extend measurement standards beyond Seoul. Even municipal partnerships can become a differentiator, as shown by JCDecaux Korea’s rapid deployment of modular bus stop units during the 2026 Lotus Lantern Festival in Jongno. In that setting, the South Korea OOH and DOOH market is likely to keep rewarding players that combine inventory access with measurable operating discipline rather than those that compete on screen count alone.
