Abstract: Systems and methods that facilitate user commentary are described. In some embodiments, a method receives program content from a content source and identifies data describing the program content. The program content is communicated to a first device for presentation to a user. The data describing the program content is communicated to a second device for presentation to the user substantially simultaneously with the presentation of the program content on the first display device. A user commentary is received from the second device. The user commentary is generated by the user and associated with the program content.

Abstract: A machine may be configured as a vehicle identification machine to identify a model of a vehicle based on an image that depicts a dashboard of the vehicle. As configured, the machine may receive an image of the dashboard, where the image depicts a layout of instrumentation within the dashboard. The machine may identify the layout of instrumentation by processing the image. For example, the machine may process the image by determining a position of an instrument within the layout of instrumentation, determining an outline of instrument, or both. The machine may access a data record that correlates a model of the vehicle with the identified layout of instrumentation and, based on the data record, identify the model of the vehicle. The machine may then provide a notification that references the vehicle, references the identified model of the vehicle, or references both.

Abstract: Offering an incentive to users of a mobile device based on the number of devices within a geographic locale. The incentive may be one or more incentives that a merchant is willing to offer only if there are a given number of users within a geographic locale. The incentive may be combined with additional incentives determined in various ways. A location identification module may determine the geographic location of mobile devices. An item identification module may identify that a merchant may be willing to offer an incentive only if there are a given number of users within a geographic locale and may identify an item specified by one or more of the given number of users within the geographic locale. An incentive module may transmit an incentive from a merchant who may or may not be within the geographic locale.

Abstract: In various example embodiments, a system and method for managing transaction in a digital marketplace are provided. In example embodiments, a transaction request involving a digital good is received. A determination as to whether the transaction involves a purchase of the digital good is performed. Based on the transaction involving the purchase of the digital good, a further determination as to whether an overlap in inventory or a related item involving the digital good exists is performed. Based on the overlap in inventory existing, a sub-collection of the inventory is created with which to complete the transaction request. Based on existence of the related item, a combination package including the digital good and the related item is created and offered in response to the transaction request.

Abstract: Multi-quantity fixed price referral systems and methods are described. A “multi-quantity fixed price” listing is a listing published by an online publication system where a seller is selling a number of identical items for a fixed price for each of the items. The methods may include selecting a category from a catalogue hierarchy used by an online publication system. The selected category may be one of a plurality of categories assigned to listings each describing an item for sale. The listings within the selected category are filtered to select a set of filtered listings. A decay formula may be applied to each filtered listing of the set of filtered listings. One or more of the filtered listings are selected based on a ranking of the filtered listings. A graphical user interface to display the selected filtered listings to the user is provided.

Abstract: User interface navigation is described. In an embodiment, an indicator displayed on a user interface rotates in place to indicate selectable directions of travel. When an input is received to stop the indicator from rotating, the indicator moves in a direction of travel. When another input is received, the indicator stops moving in the direction of travel, and again rotates in place to indicate other selectable directions of travel. An input can also be received to initiate selecting a user-selectable control on the user interface when the indicator is positioned over the user-selectable control, over a portion of the user-selectable control, or proximate the user-selectable control.

Abstract: Content ratings and recommendations is described. In an embodiment, a ratings service compiles ratings of programs for a rating system that is associated with a group of viewers, where a viewer of the group establishes the rating system, and where at least some of the viewers of the group rate the programs for the group of viewers. A recommendation service then provides program recommendations to the viewers of the group based on the rating system.

Abstract: Interactive job channel is described. In an embodiment, a viewer having a television-based client device can register an employment profile with a content provider. Employment-related media content can then be associated with the viewer according to the employment profile registered by the viewer, and when an interactive job channel is selected for viewing at the television-based client device, the employment-related media content associated with the viewer is provided by the content provider for viewing on the interactive job channel.
