GOM Player (Gretech Online Movie Player) is a freeware media player for Microsoft Windows. Key strengths are the ability to play the majority of media files without the need to obtain a codec, and the ability to play some broken media files, both advantages over traditional players, like Windows Media Player. GOM player can also play .flv files. It was created by the Gretech Corporation of South Korea.

Codec finder

For audio/video files that GOM Player can not play due to a missing codec, GOM Player will try to find one using GUID. Once it finds a match, it will direct you to a webpage where you can download and install additional codecs.

Broken or incomplete files

GOM Player can play AVI files that are being downloaded or have a broken index using its patented technology. (Patent number 10-0440495-0000, granted on July 5, 2004 in Republic of Korea)


GOM TV is a popular streaming service in South Korea, and as the most attractive feature in GOM Player, it is chiefly responsible for GOM Player's overwhelming popularity in South Korea. The GOM TV service offers users various video contents ranging from National Geographic documentaries and television dramas, to major motion pictures and adult videos.

The service mixes both ad-supported and pay-per-view content. Prices range from 500 won and up, with most movies available for 2,000 won. (1,000 won is approximately US$1.08.) [ [http://finance.yahoo.com/currency/convert?amt=1000&from=KRW&to=USD&submit=Convert finance.yahoo.com] ]

While functionality is very similar in the English and Korean versions of GOM Player, GOM TV is absent in the English version.

The latest release of GOM Player (V 2.1.9) allows American users to connect to the GOMTV StarLeague (a channel of GOMTV) to watch the latest matches of StarCraft leagues played in South Korea. This new addition to the American release was tested during the GOMTV Star Invitational which was aired in the month of February. Despite this new addition, the GOMTV service still remains absent from the American release (and those who watch StarCraft matches must use the website to connect to the streaming servers).

Popularity in South Korea
