Dramas from the public service broadcasters based on books consistently bring in bigger audiences than those that are not, a trend driven by certain genres, especially detective mysteries and thrillers.

A greater volume of newer book IP is being developed into programming, but this preference is not necessarily reflected in audience figures.                                 

Younger demographics are less enamoured with dramas based on books than older viewers. There are however notable exceptions, while attracting younger audiences may have more to do with the age, genre, and fame of the IP.
