Abstract: A method and apparatus for assuring delivery of paid advertising to a user may involve asking a question about an advertisement or requiring data about the advertisement to be entered. In one embodiment, a human presence indicator, such as stylized letters, may be displayed during or after the presentation of an advertisement to be copied by a user to indicate presence during the advertisement. When the challenge relating to ad viewing is correctly answered, a value associated with viewing the ad may be credited to a user account, either locally or at a clearinghouse or other repository.
