Kim Yu-sik

Thanks to his journalist father, he encountered computer earlier than other children. In early 1980s, in his sixth grade at elementary school, he learned to use a computer at Hagwon. In the 1990s, gaining reputation on internet by humorous posts on HiTEL's humor board, he decided to make money from the internet, and went abroad to study at Japan's Shinjuku Information Business School, but dropped out, disappointed that it taught using Japanese word processors on XT-16-bit computers instead of website creation. He grew a business on selling Japanese electronic devices and Game/Movie CDs to Korean PC network's buy/sell board on a high price. After returning to Korea in 1995, he started posting laptop user reviews on HiTEL's notebook club.

HiTEL suggested him to write laptop reviews on World Wide Web. He created two websites, one about laptops and one about Digital cameras. The latter is DC Inside, while the former Notebook Inside (Korean: 노트북인사이드) is soon closed.[1][2]
