Abstract: Advertisements are distributed by embedding them in a computer program and e-mailing the program to a user. When the program is run, it requests consent from the user to send a copy of itself to the user's contracts, such as those found in the user's local address book. On receiving consent, the program automatically mails itself to those contacts directly or via a remote server. The process is repeated at the contacts, allowing the advertisements to spread efficiently while maintaining the legitimacy that arises from each user's consent.
