Naver is a South Korean online platform operated by the Naver Corporation. It was launched in 1999 as the first web portal in South Korea to develop and use its own search engine. It was also the world's first operator to introduce the comprehensive search feature, which compiles search results from various categories and presents them in a single page. Naver has since added a multitude of new services ranging from basic features such as e-mail and news to the world's first online Q&A platform Knowledge iN. As of September 2017, the search engine handled 74.7% of all web searches in South Korea and had 42 million enrolled users. More than 25 million Koreans have Naver as the start page on their default browser and the mobile application has 28 million daily visitors. Naver has also been referred to as 'the Google of South Korea'.
