KOG is a South Korean game developer founded in 2000, best known for the online action games Grand Chase and Elsword. Its logo sting has appeared at the start of trailers, updates and gameplay videos for those titles for many years, so long time players associate the sound with logging in and new content drops. As clips were shared on soundboards and in fan videos, the short ident escaped its original context and became a reusable intro sound for gaming creators far beyond the original community.
