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.
