Abstract: Methods and apparatus for automatically developing a package of advertising spots from a plurality of available spots offered by a plurality of media suppliers are disclosed. In one implementation, an apparatus includes a package developer cooperating with the memory to develop a package containing a subset of the representations of the available spots based on at least one of a plurality of guideline variables. The apparatus also includes a validator cooperating with the package developer to validate the package by ensuring that every media supplier associated with the representations in the subset supplies a minimum percentage of the spots in the subset.
