A method of determining correlations and causality between media program content and consumer responsiveness involves identifying and storing media and commercial program time occurrence and content information and consumer media reviewing actions which occur in connection with the media and commercial program time occurrence and content information. The information is correlated to obtain and assign responsiveness probability values corresponding to type and intensity of consumer response for each of the media and commercial program time occurrence and content information. These responsiveness probability values are then applied to a second media program to place product advertising at a specific time within specific content therein as determined by the responsiveness probability values thus facilitating creation of new ads and modification of existing ones and further, directing placement of those advertisements within any and all broadcast and Internet media programming.
