Abstract: A system draws an inference about the audience being targeted by the buyer of an advertisement placement opportunity by correlating the order for the advertisement placement opportunity with characteristics of the audience associated with the television program in which the advertisement placement opportunity is embedded. Sellers of advertisement placement opportunities may use the inferred target audience information to appropriately price their advertising inventories and to fulfill orders more effectively.

Abstract: A computer system uses data about delivery of particular content to users via multiple technology platforms. For example, the computer system may track delivery of particular content to an audience via television in order to enable the same or similar content to be delivered to the same or similar audience via a digital medium (e.g., the web), and vice versa. The computer enables the provider of the content (e.g., advertisement) to benefit from exposure data in one medium or technology platform—namely television or digital—when targeting content at viewers in the other medium or technology platform.

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.

Abstract: A computer system dynamically generates pricing data, such as bid floor prices and/or bid prices, for advertisement placement opportunities based on attributes of inventory sources (e.g., televisions and computers) and of the environment associated with the instance of viewership for delivery of advertisements to those advertisement placement opportunities. An example of such attributes are attributes of the content currently being delivered by the inventory sources. The computer system enables such pricing data to more accurately reflect the value of the environment for placing advertisements.
