Amazon said the "Hunger Games" trilogy this month passed the seven-book "Harry Potter" series in combined print and Kindle sales.
"This series is only three books versus Harry Potter's seven, and to achieve this result in just four years is a great testament to both the popularity of the work and, we think, the growth in reading digitally during that time," Sara Nelson, editorial director for Amazon.com said in a written statement.
All three "Hunger Games" books remained in the top 50 of Amazon.com's best selling books in both Kindle and print formats.
