Korean TV Stations: Super Action TV

So it is really difficult to find some information in English about Super Action TV. The South Korean TV channel is owned by CJ E&M as well and is therefore connected to Mnet, OCN and tvN. It rarely airs any series that are produced for the channel itself but tends to rerun action programs that aired in some of its sister channels. It seems, however, that Super Action is most commonly known  for airing any kind of Action series and Martial Art fights.

The most popular TV series that aired on Super Action seems to be Holy Land.

As for it's own TV series, it is most commonly known for the crime genre. The most commonly known series include God's Quiz, Vampire Prosecutor, The Virus, Special Affairs Team TEN and Dr. Frost. 

*I'm in a love-hate-relationship with OCN. Their dramas are awesome but it takes ages until all the episodes as subbed and they keep delaying the next TEN season (there will be a third season.. as well as there'll be a third season for Vampire Prosecutor)..
