A techno-thriller or technothriller is a hybrid genre drawing from science fiction, thrillers, spy fiction, action, and war novels. They include a disproportionate amount (relative to other genres) of technical details on their subject matter (typically military technology); only hard science fiction tends towards a comparable level of supporting detail on the technical side. The inner workings of technology and the mechanics of various disciplines (espionage, martial arts, politics) are thoroughly explored, and the plot often turns on the particulars of that exploration. This genre began to exist and establish itself in the early 20th century with further developments and focus on the genre in the mid 20th century.
