Graph description The line graph demonstrates the book sales of adult fiction in the USA during the period from 2008 to 2012. The sales of hardcover books remained almost the same, fluctuating around 1 billion dollars per year, rising a little bit in 2009 up to around 1.2 billions and then dropping a bit to less than 1 billion in 2012. The sales of paperback editions, however, showed various ups and downs. They started from around 1.3 billion dollars in 2008, then quickly reached a point of 1.5 billions in 2010 and then suddenly dropped to 0.9 billion in 2011 continuing to fall. Unlike the previous two, e-books sales demonstrated a completely opposite trend. They rocketed during the whole period from 0.1 billion in 2008 to more than 1.8 billions of dollars in 2012. To sum up, while sales of hardcover and paperback editions fluctuated around the same numbers experiencing some uprise and downward trends and overall slightly dropping with time, e-books have been bringing more and more profit to the sellers every year.
