For K-pop artists, video platforms like YouTube have long been a stage and broadcast station, with most artists releasing new songs and performance videos for their fans. Additionally, idols continue to appear on popular web variety shows.

Short-form content has recently emerged as a new promotional tool for artists, particularly among younger viewers. According to YouTube, artists who actively post short videos see significant increases in subscriber counts and exposure to their music.
