It only took them a decade to come around. Walmart has decided to begin providing its U.S. sales data to outside parties, including research firms we care about such as Nielsen and NPD Group. All this is according to a report in Advertising Age.
For the last 10 years, NPD has been unable to provide data for retail game sales at Walmart and its Sam's Club stores, leaving a gaping hole in the numbers that firms such as NPD provides. With access to the Walmart and Sam's Club data, NPD could provide a more detailed picture of how video games are performing at retail in the U.S.
Nielsen has said that it will start providing Walmart and Sam's Club data to its clients in "a few months." NPD has not commented officially on this story.
