National Syndication commercial occurrences are identified through an automated cross-market comparison of ad placements within syndicated program telecasts. The matching process takes into account the fact that a syndication telecast airs at different times and/or on different dates across markets. After telecasts have been matched and the national ad occurrences within them have been identified, our systems align the cleared airings across markets and determine the most common airtime (adjusted for time zone). This most common time appears in reports as the airtime of a National Syndication ad occurrence.

Expenditure Data

Effective with January 2018 data, expenditures for national Syndication advertising are primarily derived from data obtained through the SQAD NETCOSTS system. Vivvix receives a monthly report detailing the average cost of a 30-second spot broken out by syndicator, program category and program sub-category. The report is based on actual spot purchases made by NETCOST contributors and reflects negotiated costs, the actual weighting of upfront and scatter buys, and the incidence of no-charge spots. T

he NETCOST inputs are entered into a proprietary model to produce an average 30-second cost for each national Syndication program.

Prior to January 2018, Syndication expenditures were derived from 30-second cost information, at the program level, supplied by contributing media agencies.

Caution: Expenditure estimates produced by these two methodologies are not directly comparable, thus causing trending disruption.
