Definition of horizontal marketing system (HMS)

joining of two or more corporations on the same level for the purposes of pursuing a new marketing opportunity. Usually a horizontal marketing system is established so that the individual members can combine resources to make the most out of the marketing situation. Products from each member can be marketed and/or distributed together, such as a bottle manufacturer combining with a producer of dehydrated salad dressing preparations. The two products are marketed together, allowing the two companies to combine their marketing resources and accomplish much more than either one might accomplish alone. Corporations in a horizontal marketing system also have the option of combining their capital and production capabilities, in addition to their marketing and distribution resources, to produce synergistic benefits for all members.
