What term describes a cheap sensational novel popular in the 19th century that was often issued in instalments?

The term that describes a cheap sensational novel popular in the 19th century, often issued in installments, is "Penny Dreadful." This genre emerged in Victorian England and was characterized by its focus on sensational and sensationalized content, which included horror, crime, and adventure stories designed to entertain readers quickly and affordably. The format allowed for stories to be published in serialized form, appealing to a growing readership that craved thrilling narratives at low prices.

While "Dime Novel" is also relevant as it refers to cheap novels popular in America during the same period, the "Penny Dreadful" specifically emphasizes the sensational aspect and the cultural context of British literature at the time. Gothic Fiction, although it overlaps in themes such as horror and the supernatural, refers to a broader genre and not specifically to the popular, sensationalized format. Similarly, while "Serial Narrative" correctly describes the form of storytelling, it does not capture the cultural and economic implications associated with the "Penny Dreadful" label. Thus, the distinct characteristics of sensationalism and affordability uniquely position "Penny Dreadful" as the most accurate answer.
