Support advertising — also called a fan ad, a birthday ad, or 응원광고 — is when fans pool their money to display an ad for their favorite idol in public places in Korea, to celebrate a birthday, debut anniversary, or comeback.
In Japanese these ads are called センイル広告 ("senil") — borrowed from the Korean word 생일 (saeng-il), meaning "birthday".

Pick one, or combine a few — we'll recommend the best fit for your date and budget.
