BookScan is a data provider for the book publishing industry that compiles point of sale data for book sales, owned by Circana in the United States and NIQ in the United Kingdom, Ireland, Australia, New Zealand, India, South Africa, Italy, Spain, Brazil, Mexico, and Poland.
The New York Times would survey hundreds of outlets to estimate which books were selling the most copies, and would publish rankings but not figures.
[8] NIQ was formed from the divestiture of consumer intelligence business of the Nielsen Holdings (known as NielsenIQ) to private equity firm Advent International in March 2021.
Slate noted that Jane Austen's Pride and Prejudice was available from Amazon in 130 different editions; prior to BookScan there was no way to tabulate total sales.
[10] NIQ offers the BookScan service in 10 territories outside the U.S.: the UK, Ireland, Australia, New Zealand, India, South Africa, Italy, Spain, Brazil and Mexico, with Poland next to launch.
