This time, we are in Hongdae to take a close look at the birthday support advertisement for Magenta, a member of the Korean girl group QWER.
This campaign is placed on Digital Signage media in the transfer passage of the AREX (Airport Railroad) at Hongdae, Seoul. As it connects Line 2, the Airport Railroad, and the Gyeongui–Jungang Line, it draws large numbers of commuters, local young people, and international travelers every day, making it one of Seoul’s busiest transport hubs.




Digital Signage is a large-format digital advertising medium. This placement is located at a corner area and features a three-sided screen design. No matter which direction passengers approach from, the ad content is clearly visible, delivering excellent exposure and strong visual impact.
This campaign also fully showcased the birthday support design that BAWIGE carefully prepared for MAGENTA, attracting many fans and passersby to stop and watch.
