Tying (informally, product tying) is the practice of selling one product or service as a mandatory addition to the purchase of a different product or service. In legal terms, a tying sale makes the sale of one good (the tying good) to the de facto customer (or de jure customer) conditional on the purchase of a second distinctive good (the tied good). Tying is often illegal when the products are not naturally related. It is related to but distinct from freebie marketing, a common (and legal) method of giving away (or selling at a substantial discount) one item to ensure a continual flow of sales of another related item.
Horizontal tying is the practice of requiring consumers to pay for an unrelated product or service together with the desired one.[1] A hypothetical example would be for Bic to sell its pens only with Bic lighters. (However, a company may offer a limited free item with another purchase as a promotion.
Vertical tying is the practice of requiring customers to purchase related products or services together, from the same company.[1] For example, a company might mandate that its automobiles could only be serviced by its own dealers. In an effort to curb this, many jurisdictions require that warranties not be voided by outside servicing; for example, see the Magnuson-Moss Warranty Act in the United States.
The Wikipedia Tying entry[1] also makes references to both Apple and Microsoft products. Of particular interest was how Microsoft not only ties their own products, but also ties Android OEM's, who they shake down to license their patents, to bundle their Microsoft mobile applications.
>Microsoft has also tied its software to the third-party Android mobile operating system, by requiring manufacturers that license patents it claims covers the OS and smartphones to ship Microsoft Office Mobile and Skype applications on the devices.
