Market segmentation, targeted marketing

An  epublisher of a  new song wanted to do an email campaign to likely candidates that would purchase the song online and download it. They assumed that the target audience is male between 18 and 25 who must have access to email. Further, refine this group to those that have already previously purchased and downloaded music online . By using Set'Graph, in just minutes, they found  the number of Males 18 to 25 with access to email and who download music off the Internet (the white region). The epublisher then used "drag and drop"  of the target region (white) onto a worksheet to produce a marketing and sales list.

... we could refine our market further by such additional criteria as musical interest, or other conditions that  exist in the database.
