**PC Data** was an American [market research](/source/Market_research) and [point of sale](/source/Point_of_sale) tracking firm founded in 1991 and based in [Reston, Virginia](/source/Reston%2C_Virginia). Its founder, Ann Stephens, had worked previously as the head researcher for the [Software Publishers Association](/source/Software_Publishers_Association). Initially, the firm tracked only the United States' computer software market,[1] but later expanded to include hardware sales and, in 1999, Internet traffic.[1][2] By 1996, *[The Washington Post](/source/The_Washington_Post)* described PC Data as "the preeminent tabulator of facts and figures of the monthly sales of consumer software in the United States".[1] Its coverage of the United States retail software sales market had grown to 80% by September 1998.[3]

In March 2001, [The NPD Group](/source/The_NPD_Group) purchased PC Data's point-of-sale research branch and merged it with its Intelect Market Tracking division.[4][5] Following a legal settlement with the rival company Jupiter Media Matrix regarding [patent infringement](/source/Patent_infringement), PC Data ceased Internet traffic research and closed later in March.[6][7] Firms NetValue and [ComScore](/source/ComScore) purchased the remainder of PC Data's Internet research branch.[7]
