Abstract: A method for determining the relationship between historical media support levels, media cost or spending, product pricing and product sales that provides the relative effectiveness and efficiency of a specific form of media at both a macro and micro level, as well as an understanding of media half-life and media saturation points. This method measures all known forms of media such as the commonly used media of television, radio and newspaper, as well as new forms of media advertising such as internet banners and email along with lesser used media like sides of buildings and taxi tops.
