A photonovel (sometimes spelled as fotonovel) is a type of book, adapting a film or television episode and using film stills instead of artwork along with the narrative text and word balloons containing dialogue. The photonovel concept was most popular in the late 1970s and early 1980s, before the widespread advent of home recording devices such as VCRs, though some are still published. Several popular films and television programs were adapted to the format.
