Webtoon ( Hangul: 웹툰, RR: wep-tun) is a term used to describe South Korean webcomics or manhwa that are published online. The Korean web portal Daum created a webtoon service in 2003, as did Naver in 2004. These services regularly release webtoons that are available for free. According to David Welsh of Bloomberg, comics account for a quarter of all book sales in South Korea, while more than 3 million Korean users paid to access online manhwa and 10 million users read free webcomics.
, Naver had published 520 webtoons while Daum had published 434. Since the early 2010s, services such as Tapastic, Spottoon and Line Webtoon have begun to officially translate webtoons into English. Examples of popular webtoons that have been translated into English are The Breaker, Girls of the Wild's, The Gamer, Noblesse, and Tower of God. In recent years, these webtoons have been gaining popularity in Western markets, rivalling Japanese manga.
As digital comics have emerged as a popular medium, print publication of manhwa has decreased. The amount of material published in webtoon form has now reached an equal amount as that published offline.
