"I want to celebrate Stray Kids members with support ads." "I want to put out a birthday ad, but I don't know where to start." To answer such STAY's wishes, this guide explains everything from the basics of support ads to the application process.
What are Stray Kids support ads? (Quick reference for 8 members' birthdays)
Support ads (sen-il ads) are a cultural phenomenon where fans purchase advertising space at stations, on streets, and other public places at their own expense to express their love for their favorite artists on their birthdays or anniversaries.
| Member Name | Birthday |
|---|---|
| Bang Chan | October 3 |
| Lee Know | October 25 |
| Changbin | August 11 |
| Hyunjin | March 20 |
| Han | September 14 |
| Felix | September 15 |
| Seungmin | September 22 |
| I.N | February 8 |
September sees a succession of birthdays for Han, Felix, and Seungmin, making it a popular time for STAYs to consider joint projects or multiple ad placements. Starting preparations 2 to 4 weeks before the birthday allows for sufficient time to place the ad.
