At the Open Data 2007 Conference in New York, David Cancel, the CTO of the web market research firm Compete Incorporated, revealed that many Internet service providers make millions by selling the clickstream data, meaning every web site visited by each user and in which order they were clicked, of their users. The data is not sold with accompanying user name or information, but merely as a numerical user value. However, it is still theoretically possible to tie this information to a specific ISP account. Cancel said that this clickstream data is "much more comprehensive" than data that is normally gleaned through analyzing search queries.
