Naver (Hangul: 네이버) is a popular sponsored advertisement portal in South Korea, owned by Naver Corporation. Naver was launched in June 1999 by ex-Samsung employees, and it debuted as the first Web portal in South Korea that used its own proprietary search engine. Among Naver's features is "Comprehensive Search", launched in 2000, which provides results from multiple categories on a single page. It has since added new services such as "Knowledge Search", launched in 2002.
