Abstract: In one embodiment, a method includes determining television content that a particular user is currently watching on a television and determining, using one or more sensors, an attention level for the particular user. The attention level indicates an amount of attention paid by the particular user to the television content. The method further includes generating an attention profile for the television content by aggregating the particular user's attention level for the television content with stored information associated with a plurality of other users about the television content. The attention profile indicates a number of users who paid attention to the television content. The method further includes determining digital content available on a social-networking system that is related to the television content and providing a comparison of the number of users who paid attention to the television content with engagement on the social-networking system with the related digital content.
