The bar graph shows annual sales of non-fiction books, fiction books, magazines, journals, and bookstores every year since 1990.
By and large, non-fiction books are the highest of the period, and book sales in all classes apart from journals were an increasing trend seen over the period. All in all, there are significant changes in non-fiction book sales, and journal sales decline slowly. Fiction and magazines were relatively flat.
Looking at the graph more closely, non-fiction was the dominant genre, for approximately more than three times all sales in each period. Non-fiction remained almost constant, the only drop was in 1998 when sales dropped insignificantly by roughly 1000 books. A similar pattern was seen in the middle with fiction and magazines, capturing just 1,000 to 4,000 in total.
Dissimilar to the other categories, journals dipped minimally and did not show an upward trend. Journals consistently stayed around 10 per cent over the span of 10 years.
