Afreeca is a video streaming service based on P2P technology, owned and operated by Nowcom in South Korea. The site mainly retransmits TV channels, but also allows users to upload their own videos and shows. The head of Afreeca's parent company Nowcom, Mun Yong-sik, was arrested in 2008 for illegally distributing pirated films. Some alleged the arrest was politically motivated due to Afreeca being used by protesters to coordinate.
