Nielsen SoundScan is an information system created by Mike Fine and Mike Shalett that tracks sales data for singles, albums, and music video products in Canada and the United States for Billboard and other music industry companies. MTV, VH1, and many other north American cable music channels use Nielsen SoundScan data as well.
Nielsen SoundScan began tracking sales data for Billboard on March 1, 1991. Previously, the Recording Industry Association of America tracked sales by calling stores across the U.S. and asking about sales.
A barcode is on the back of every CD or cassette. When the Canadian/U.S. customer is about to buy an album or single, the store clerk runs the barcode across a scanner. The sale is put into the store's computer and the sale data is also sent to Nielsen Media Research offices for the region.
Nielsen SoundScan clients include:
In 2005, single sales have fared better than they have in years since Billboard started tracking digital downloads from online music stores such as iTunes, Rhapsody, and Musicmatch. Sales of digital downloads have increased more than 200% from last year; however, sales of CD singles are down about 60% from last year.
