Replying to the discussion forum.  
Discussion Topic
How can/should the concepts of segmentation, targeting and positioning be used to businesses’ advantage in their strategic marketing activity (you do not necessarily have to cover all of segmentation and targeting and positioning in a single post – depth is usually better than breadth)? Give examples of how businesses in different market sectors use these concepts, or could do so.
