Abstract: A social networking system aggregates content related to the media events that have aired or are currently airing from a variety of sources, such as the entity broadcasting the media event and users that author content items referencing the media events. The social networking system generates multiple event interfaces that allow users of the social networking system to consume content, both user authored content and content curated from external sources, related to a media event. The interfaces include both content items that have a high correlation with the media events and visual representations of the user response to media event. Further, the interfaces include interface elements that allow users to easily navigate and interact with the information being presented as well as provide additional content related to the media events.

Abstract: A computer system provides a virtual marketplace in which an advertising opportunity (such as a television advertising opportunity) is expressed in terms of an audience model representing an audience associated with the advertising opportunity. The computer system provides potential buyers of a particular advertising opportunity with information about the audience model associated with that advertising opportunity. The computer system sells advertising opportunities to buyers using any of a variety of transaction semantics. A buyer who purchases a particular advertising opportunity purchases the opportunity to present an advertisement to an audience represented by the audience model associated with the purchased advertising opportunity.
