A server receives a source signal stream comprising metadata and an advertisement space. The server extracts from the metadata a channel identifier, a private client identifier, and personal identifiable information about an intended audience of interest to advertisers. The server identifies at least one anonymous statistic of a national market and a placement opportunity including an owner of the advertisement space, the at least one anonymous statistic of a national market based in part on the channel identifier and the personal identifiable information. The server purges the personal identifiable information about the intended audience when the owner of the advertisement space is identified as a national network. The server targets an advertisement decision to the intended audience based on the at least one anonymous statistic of a national market.
