vertical marketing 纵向营销
　　 　　
1) a marketing process in which planning and operations are coordinated to include manufacturers, wholesalers, and retailers
2) the practice of selling to a very limited segment of a market, such as affluent professionals in a particular region
　　
EXAMPLE:
1) The vertical marketing campaign for our new wireless technology required more coordination and careful timing because we needed to insure that the available supply of our products could immediately meet the high demand we were expecting.
2) The expensive housecleaning service company determined that most of their customers were wealthy doctors and executives in the capital, so they developed a vertical marketing strategy targeted to a few affluent neighborhoods.
