Television transmissions are received at multiple locations across a large area. Advertisements may be identified, harvested and tagged from within in the television transmissions. The advertisements may be assigned identifiers; media plans may be determined. Advertisement representations (e.g. fingerprints) may be used to identify advertisements in television content received by the smart TVs. The smart TVs may report the fingerprints along with other identifiers or samples thereof. Television content and advertisements therein as rendered by the smart TVs may be categorized as live, timeshifted, on-demand, over-the-top, and the like. The advertisements may be categorized as occurring in national or local/regional ad slots. The data from the smart TVs may be used to determine ad impressions, gross rating points, and target rating points. View rates for advertisements may also be determined and variations of advertisement may also be prepared.
