Method of advertising on-line during, for example, a world wide web session
is provided by downloading full page advertisements from a predetermined site (e.g.,
remote server) to a user's computer during a communication link idle time. The
downloaded advertising data are stored and then displayed when the user makes a
request to retrieve new data, for example, a hyperlink request to a selected remote
server. The advertisement remains displayed while the connection to the selected
remote server is made and at least until a portion of new content data is transmitted
to the user terminal.
