Market Overview

The South Korea OOH and DOOH Market represents a vibrant segment of the country’s advertising and media industry. Out-of-home (OOH) advertising refers to all forms of advertising that reach consumers outside their homes, including billboards, transit ads, street furniture, and venue-based signage. Digital out-of-home (DOOH) takes this a step further by incorporating digital displays, programmatic advertising, real-time data, and dynamic content.

As one of Asia’s most technologically advanced nations, South Korea has rapidly embraced DOOH, particularly in urban centers like Seoul, Busan, and Incheon. High smartphone penetration, advanced connectivity, and data-rich environments make the country ideal for innovative outdoor advertising strategies.

Amid evolving consumer behavior and growing digitalization, advertisers are increasingly turning to OOH and DOOH formats to deliver high-impact, non-intrusive, and contextually relevant campaigns in public spaces.

Meaning

OOH (Out-of-Home) advertising encompasses traditional static media displayed in public spaces, while DOOH (Digital Out-of-Home) includes dynamic content delivered via digital screens in similar environments. These formats offer:

• High Visibility: Reaches a broad audience in public and semi-public areas.

• Targeted Messaging: DOOH enables real-time content changes based on audience, weather, location, and more.

• Brand Awareness: Builds top-of-mind recall through repetitive and large-format displays.

• Data-Driven Campaigns: Integration with mobile and social platforms enhances engagement and performance tracking.

In South Korea, OOH and DOOH are widely used across retail, automotive, entertainment, telecom, government, and financial services sectors, making them integral to the country’s media landscape.

Executive Summary

The South Korea OOH and DOOH Market is estimated to reach USD 2.8 billion by 2030, up from USD 1.9 billion in 2024, growing at a CAGR of 6.7% during the forecast period. DOOH is the fastest-growing segment, accounting for over 40% of the total market, and is expected to surpass traditional OOH in revenue share by 2028.

Growth is driven by urbanization, smart city developments, 5G adoption, and increased use of AI and programmatic technologies in advertising. With the government investing in smart infrastructure and private companies deploying high-resolution LED screens in high-traffic areas, South Korea is setting a regional benchmark for innovation in the OOH space.
