툰코 is a type of digital comic or graphic novel that originated in South Korea and is designed to be read online, typically on smartphones or computers. The term "webtoon" is a blend of "web" (referring to the internet) and "cartoon." Unlike traditional printed comics, webtoons are usually presented in a vertical scroll format, making them easy to read on digital devices. They often feature vibrant artwork, diverse genres (such as romance, action, fantasy, and horror), and are frequently updated in episodes or chapters.

Webtoons have gained immense popularity worldwide due to their accessibility and the wide variety of stories they offer. Many platforms, such as Naver Webtoon and LINE Webtoon, provide free or paid access to these comics, allowing creators to reach a global audience. Some popular webtoons have even been adapted into dramas, animations, or movies, further expanding their influence in entertainment.

In summary, a webtoon is a modern form of digital storytelling that combines art and narrative in a format tailored for the digital age.
