SBS

SBS (Seoul Broadcasting System, 에스비에스) is South Korea's largest private commercial terrestrial broadcaster and one of the three network pillars that still shape mass-market television in Korea. Since launching in 1991, SBS has built its business around advertiser-scale reach, premium drama scheduling, and entertainment formats that can keep circulating long after first broadcast.

Its scripted footprint is one reason the network still matters in an OTT-heavy market. SBS helped power multiple modern drama cycles through titles like While You Were Sleeping, The Penthouse, and The Glory, while the wider Studio S production structure lets the broadcaster package series for both linear TV and streaming afterlife. That balance keeps SBS commercially relevant even as pure-play platforms compete for attention.

The network's unscripted business is just as important. Running Man remains one of Korean entertainment's most durable clip engines and international fandom brands, while SBS's larger music, sports, and live-event coverage keeps the company visible across formats. In K-culture terms, SBS is not just a channel. It is one of the core distribution machines still capable of creating nationwide hits.
