Some webtoons have become very popular. For example, Making Fiends became a series on Nickelodeon. Characters from webtoons are used on merchandise and in games. Webtoons have been made into movies, plays and soap operas.
Webtoons are particularly popular in South Korea. In the 1990s the government banned comic books as harmful to teenagers. Eventually cartoonists began adding stories in their blogs. Over time these gained commercial appeal. Technology advances allowed these cartoons to change into webtoons.
