Over times people’s values and interests change, and with that their reading taste. The image demonstrates a comparison from one bookdealer of books they have sold between 1972 and 2012.
The given data shows very smooth changes in percentages of children’s fiction, travel, and others literature, and a dramatic change in adults’ fiction and biography books.
The adults’ fiction has experienced a massive rise from being not at the top of interest in 1972 and 1992 staying around 20-25%, to the biggest preference of customers in 2012 becoming 45% of all sold books. However, there’s also a lowering interest in biography books that went smoothly from 20% in 1972 to only 8% in 30 years, and others that, unfortunately, fell from 25% in 1972 to 12% in 2012.
The charts also illustrates some quite stable statistic in many types of books, for instance, children’s fiction that through all given time hovered around 20-25%, and travel books that has only rose from 15% to 18% since 1972 until 1992, and then dropped back to 10% in 2012.
