Abstract: An internet-based content platform that includes subscribable channels is provided. The internet-based content platform provides channels to end users. Prices are defined for including one or more channels in one or more composite channels. The prices may be provided to channel curators associated with the one or more composite channels and the one or more channel curators may accept or reject the prices for including the one or more channels in the one or more composite channels.

Abstract: Systems, methods, and media for presenting advertisements are provided. In some implementations, systems for presenting advertisements are provided, the systems comprising: at least one hardware processor that: receives media content containing a video portion and/or an audio portion; determines whether a watermark is embedded in at least one of the video portion and/or the audio portion of the media content; and if it is determined that the watermark is embedded in the at least one of the video portion and/or the audio portion of the media content: identifies a payload in the watermark; receives an advertisement selected at least in part based on the payload; and causes the advertisement to be presented instead of the media content.

Abstract: A video hosting service stores and provides video content to a client via a network. Advertisers search for videos to target by entering search criteria into a user interface. Advertisers can search based on characteristics of the audience (viewers) of the videos, such as age range, gender, and interests of the viewers, and/or based on metadata associated with the videos. A set of videos that meet the search criteria is then retrieved. Advertisers can select individual ones of these videos or groups of these videos. The selected videos or groups of videos can be added to a media plan. The items from the media plan can be imported into an advertising campaign management system, wherein the advertiser's ads are associated with the selected videos. Subsequently, viewers who view the selected videos also view the advertiser's ads in connection with the videos.

Abstract: A computer user interface may be used to create and maintain semantic relationships between data objects on a computer system. Multiple sets of data objects identified by user selections, queries, searches, or other criteria may be presented in display panes on the user interface. Users may then select data objects via the user interface in order to view or create new relationships between the data objects. Based on the selection of the data objects and a determination of the associated data object types, a set of semantic relationships applicable to the selected data object or objects may be retrieved and displayed in the user interface. A user may subsequently select and create an appropriate semantic relationship between data objects, thereby not only establishing an association between the objects, but providing a specific and useful meaning to the association.

Abstract: When displaying various types of information, an application may identify whether any related entities exist. For example, when displaying an e-mail message, the sender information may relate to a contact entity. As such, information associated with the contact entity may be displayed along with the message. The related entity data (e.g., contact entity data) may be displayed in a subregion of the display area corresponding to the parent entity data (e.g., an e-mail message information) and/or differentiated in various manners. An application interface may further be configurable to control an amount of related entity data that is displayed. A property picker system may also be used to allow a user to specify the properties that he or she wants to make available for display in the interface.

Abstract: A data organization system comprises an interface component that receives input that relates to properties associated with a first item type. A set generator component filters a collection of items of the first item type as a function of select properties associated with the input and creates and stores a first filtered set of items of the first item type. The first filtered set of items can, for example, be stored as one of a dynamic set and a static set.
