End-of-life is a term used with respect to a product supplied to customers, indicating that the product is in the end of its useful lifetime and a vendor will no longer be marketing, selling, or sustaining a particular product and may also be limiting or ending support for the product. In the specific case of product sales, the term end-of-sale has also been used. The term lifetime, after the last production date, depends on the product and is related to a customer's expected product lifetime. Different lifetime examples include toys from fast food chains, cars, and mobile phones. Product support during EOL varies by product. For hardware with an expected lifetime of 10 years after production ends, the support includes spare parts, technical support and service.
