The study by researchers at the University of California-Berkeley (PDF*), which was released late Monday, indicates that Web users may be tracked ("bugged," as the researchers put it) by dozens of sources on a visit to a single site. In a single month, they found 100 monitoring agents on one site, blogspot.com.

"We sent each company a request via email or an online Web form for a list of each affiliate they may share data with. We received 14 replies, but none included the lists we asked for.
