We were recently honored to participate in and assist with the placement of CM Board birthday support advertisements for Siyeon and Magenta of the South Korean girl group QWER in the Seoul Metropolitan Subway.
This advertisement was placed at Gangnam-gu Office Station, a popular transportation hub in Seoul. Due to its proximity to the Gangnam commercial district and steady foot traffic, it has consistently been one of the most popular stations for South Korean subway advertisements and birthday support ads.
CM Board is a vertical digital screen medium. Compared to other media in the Gangnam area, the entry threshold for CM Board is relatively accessible, making it one of the most popular and cost-effective advertising media.
If you wish to increase exposure or prefer not to use a rotation format, you may also choose to place a CM Board light box advertisement. (Positioned to the left of the pillar in the image below)
