HS Ad is an LG Group-affiliated advertising agency founded in 1984 that originated from LG Ad and adopted its current name in 2023 after absorbing HS Ad and Elbest.
Its core business is production of advertising materials and media buying across the four traditional media, providing services through overseas subsidiaries and branch offices worldwide.
The company has made digital transformation a core priority, using its proprietary DASH X and DASH.AI platforms to respond to digital innovation.
While LG Group-affiliated advertising volume forms a stable revenue base, the company has recently secured new non-affiliate clients such as Dunamu and Jeisys Medical, expanding into finance, beauty, gaming, pharmaceuticals, sports, and public-sector accounts.
Industry observers note that large conglomerate-affiliated agencies are increasingly pursuing non-affiliate clients to secure a more stable revenue base amid rising volatility in affiliate business.
In brand reputation surveys of listed advertising companies, HS Ad frequently ranks in the upper tier, following Cheil Worldwide, Innocean, SM C&C, Incross, and KT M&S.
Korea's advertising market is being reshaped around digital advertising, which now accounts for more than 60% of the total, and HS Ad is responding by strengthening its role as a marketing orchestration partner leveraging AI technologies.
In 2026, the company also expanded its scope of business to include generative-AI-based content production and copyright agency services.
