The video discusses permission marketing which is a term used in e-marketing. Marketers will ask permission before they send advertisements to prospective customers. It is used by some Internet marketers, email marketers, and telephone marketers. It requires that people first "opt-in", rather than allowing people to "opt-out" only after the advertisements have been sent.
