UCC got more complicated when Korea's National Election Commission asked that obvious advocacy clips be taken down as they violated Korean election law during the short period when a political campaign is formally declared (link here).
Pandora which collects fees for advertising in connection with a post proposes to pay the stations half the fee and to cap the length of any video to five minutes. It has also proposed "reference rights" so it gets sued rather than the poster and "submitted a written statement to the National Internet Promotion Agency of Korea and the three national broadcasters - KBS, MBC and SBS - asking them to guarantee Web users the rights to 'freely edit' a certain part of a TV program, be it news, documentary, drama or entertainment show, in order to add fun or wit to the content."
UCC is apparently very widely created and viewed in Korea. As elsewhere, the broadcasters can benefit from the exposure as well as any fees Pandora would pay. Stay tuned.
