Network-delivered advertisements, and in particular Internet advertisements, are provided increased
accessibility and effectiveness through automatic collection of ads, and later presentation of those ads by users. Typically, a publisher modifies a source file (e.g. an
HTML file) to include the invention's
software and
metadata identifiers that uniquely identify advertising content in the source file. When the file is transferred and presented to a user, the invention's
software, operating in conjunction with presentation
software (e.g. a
web browser), locates the
metadata identifiers within the presentation (e.g. a displayed
web page) and uses them to identify the portions of advertising content associated with those
metadata identifiers. The portions of advertising content are then collected and transmitted to a
server computer that stores them in a
database so that they are associated with a user-identification code retrieved from the user's computer. The invention's software also provides each of the displayed advertisements with an associatively positioned operator control. A user of the invention may then use those operator controls to navigate among and retrieve advertisements previously viewed by that user and stored in the
server computer's
database. Additionally, a user may enter a login and
password to assign the user-identification code to additional computers operated by the user, and thereby enable collection and viewing of advisements on multiple computers. Thus, network-delivered advertisements are provided increased
accessibility and effectiveness.
