I had a constant interest in eBook since it first came out in Korea. Meanwhile, I founded an IT related device production startup company 1995. Beginning in 2010, I changed my course to join my family publishing business and got a vision to startup an eBook publishing company. I founded i-ePUB the same year and have been running the company ever since. Korean mass media recognized i-ePUB because it was the first eBook-only company in Korea and also the first eBook company to be certified and funded by a government approved venture capital investment. I was recognized for my planning and technological skills from the government and the public as well. Now I am contributing to Korean Publication Industry Promotion Agency, Korean Education and Research Information Service as an advisory committee member. Recently, I began teaching at Konkuk University Department of Cultural Contents and Gyunggi Graduate School of Electronic Contents as an Adjunct professor.
