Andy Oram writes How browsers get to know you in milliseconds "A small technological marvel occurs on almost every visit to a web page. In the seconds that elapse between the user’s click and the display of the page, an ad auction takes place in which hundreds of bidders gather whatever information they can get on the user, determine which ads are likely to be of interest, place bids, and transmit the winning ad to be placed in the page."
If you had asked me 15 years ago if this is how the web would work, never could I have thought this up.
