Abstract: Method, system, and programs for providing content to a user. In one example, the user is associated with a first user group. At least some information of the user corresponds to a first topic associated with the first user group. A second user group is then determined based on the first topic associated with the first user group. A second topic associated with the second user group is different from the first topic associated with the first user group. Content related to the second topic associated with the second user group is provided to the user.

Abstract: A recipient's viewing or listening attentiveness to an advertisement is identified and subsequent advertisements are targeted to the recipient responsive to the recipient's attentiveness. The recipient may be a viewer or a listener of an advertisement, such as a television commercial. While the recipient is viewing or listening to an advertisement, if the recipient fast-forwards through or interrupts the advertisement, then a subsequent advertisement is chosen that has a higher probability of being viewed in its entirety. Thus, the advertisements are targeted toward the recipient based on the recipient's attentiveness to certain types of the advertisements. This increases the probability that the recipient will watch an entire advertisement, making the advertisement more effective.
