A commercial is an advertising message that is broadcast on television or radio. Unlike print advertisements, which are focused on space, broadcast commercials leverage time and must creatively integrate elements such as words, sound, and music for radio; and additionally sight and motion for television.
Media weight refers to the volume of audience delivered by an advertising campaign, measured in terms of the number of commercials, advertisements, insertions, time parameters, and budget. It essentially represents the total audience reach of the advertising effort.
