The TCP/IP network in South Korea started in May 1982, one of the earliest Internet deployments in the world. The initial TCP/IP network, called SDN,

consisted of two nodes with 1200 bps bandwidth.SDN served the research and education community with primary focus on network research, and had

international links with UUCP initially. The international links cover several countries in Asia, which is called AsiaNet, as well as Europe and North America.

In parallel to TCP/IP development, the communications on personal computers using bulletin boards and others also proliferated. These two network

developments along availability of WWW made explosive Internet growth in 1990s. These developments resulted in the leading broadband country with

various applications. The Internet is becoming the social infrastructure in Korea lately with many aspects of daily life are done through the Internet including

social and political activities. Convergence of the Internet with telecommunications and broadcasting is taking place now.
