Seoul Broadcasting System (SBS) KRX: 034120 is one of four major national South Korean television and radio networks. On March 17, 2000, the company legally became known as SBS, changing its corporate name from 서울방송 (Seoul Bangsong).
On July 30, 2008, SBS gave out a programme to show a full time rehearsal of Beijing Olympic Opening Ceremony before it could be legally watched in August 8, 2008. On this programme, the rehearsal was clearly illustrated, including the show, the organization and the torch. And some sections had been uploaded to YouTube, which therefore made them available to all over the world. Though YouTube removed the videos later on, yet SBS were blamed to steal the secret, and some people and groups were even threatening to prosecute this company for harming the Broadcast Right of IOC.
