Abstract: An interchange enables advertising data to be interchanged among providers for serving the advertising data on different provider technology platforms and consumers for using the advertising data on different consumer technology platforms. The interchange includes provider connectors for connecting all the providers to a network, and consumer connectors for connecting all the consumers to the network. A host controller executes a standardized provider application programming interface (API) on the network to enable each provider to serve the advertising data via a respective provider connector over the network to at least one of the consumers, and for executing a standardized consumer API on the network to enable each consumer to use the advertising data via a respective consumer connector over the network from at least one of the providers.
