Red Herring: “DoubleClick’s cookie cache is a treasure trove for Google”

excerpt: “Without a doubt, DoubleClick’s historical data is very valuable,” says Jupiter Research analyst Emily Riley. “Every time you’re online, every page visit, and every ad you see comes with the possibility that a cookie is placed on your machine. DoubleClick has all the data.”

How much data? Ms. Riley’s back-of-the-envelope calculation puts it into the fifteen figures: with more than 100 million web users viewing a quarter million pages a year, it hits the 2.6 quadrillion mark—and that’s just U.S. users. If DoubleClick’s ad network touched even half of those interactions, it amounts to the kind of database advertisers would drool over. “What it does is complete the picture for Google about what’s happening on publishers’ web sites,” Ms. Riley says.
