Some advertisers offer certain consumers home computers free of charge  Advertisements play continuously on the computers' screens whenever they are in use  As consumers use the computers to browse the Internet, information about their browsing patterns is sent to the advertisers, enabling them to transmit to each consumer advertising that accurately reflects his or her individual interests
The advertisers can afford to offer the computers for free because of the increased sales that result from this precise targeting of individual consumers
There are at least some consumers who browse the Internet using computers offered free of charge by the advertisers and who, if they did not use those computers to browse the Internet, would spend little if any money on purchases from those advertisers.
