Comic books have evolved greatly over the years, and as such, they have been referred to by different names. One synonym for comic books is graphic novels - a term that is often used to describe a book-length work of fiction or non-fiction, which uses sequential art and graphic storytelling techniques. Another synonym that has gained popularity in recent years is the term "sequential art," a phrase coined by artist Will Eisner to describe a medium that combines words and images in a sequential form. Other synonyms for comic books include illustrated novels, comic strips, and manga (Japanese comics). Regardless of the term used, comic books remain a captivating form of storytelling, loved by millions around the world.
