Graphic fiction is a hybrid genre that combines words and sequential images. It developed from prehistoric cave paintings and woodcut novels, and became popular in comic books in the 1930s and graphic novels later in the 20th century. A graphic novel combines visual and verbal elements through image panels, text boxes, and speech/thought bubbles. Notable graphic novels include Maus, which won a Pulitzer Prize, and works by Art Spiegelman, Jason Lutes, Chris Ware, and Sarnath Banerjee. Graphic fiction is an interactive medium that encourages imagination and blends qualities of books and film.
