Celebrity comics are comics based on the fame and popularity of a celebrity. They are a byproduct of merchandising around a certain media star or franchise and have existed since the mass media and comics came into existence in the 19th century. Celebrity comics are usually not held in high esteem by critics, because of their purely commercial nature. They are solely created to capitalize on media trends and therefore published so quickly and cheaply that drawings and narratives tend to be of very low quality.
