The star balloon (별풍선) is the signature virtual gift on AfreecaTV/SOOP and one of the best-known tipping units in Korean streaming. Viewers purchase star balloons with real money and send them to a BJ during a live broadcast as a donation; the BJ later converts received balloons into revenue, with the platform taking a share. Star balloons are central to how many BJs earn a living.
Why do star balloons matter so much?
Because income is gift-driven, star balloons shape the broadcast itself. BJs often set pledges (공약) — promises to perform a song, dance, or special segment once a balloon goal is reached — turning donations into live events. Large balloon totals can also rank BJs against one another in crew competitions.
Is there an equivalent on other platforms?
Yes. PandaTV uses hearts (하트) as its gift unit, and other platforms have their own currencies, but the principle — viewers gifting a broadcaster live — is shared across Korean streaming.
