"End-of-life" (EOL) is a term used with respect to a product supplied to customers, indicating that the product is in the end of its useful life (from the vendor's point of view), and a vendor stops marketing, selling, or rework sustaining it. (The vendor may simply intend to limit or end support for the product.) In the specific case of product sales, a vendor may employ the more specific term "end-of-sale" (EOS). The time-frame after the last production date depends on the product and relates to the expected product lifetime from a customer's point of view. Different lifetime examples include toys from fast food chains (weeks or months), cars (10 years), and mobile phones (3 years).
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. Spare-part lifetimes are price-driven due to increasing production costs: when the parts can no longer be supplied through a high-volume production site (often closed when series production ends), the cost increases.
In the computing field, the concept of end-of-life has significance in the production, supportability and purchase of software and hardware products. For example, Microsoft marked Windows 98 for end-of-life on June 30, 2006. Its software produced after that date, such as Office 2007 (released November 30, 2006), is not installable on Windows Millennium or any prior versions. Depending on vendor, end-of-life may differ from end of service life, which has the added distinction that a vendor of systems or software will no longer provide maintenance, troubleshooting or other support. Such software which is abandoned service-wise by the original developers is also called abandonware. Sometimes, software vendors hand over software on end-of-life, end-of-sale or end-of-service to the user community, to allow them to provide service and further upgrades themselves. Notable examples are the web browser Netscape Communicator, which was released 1998 by Netscape Communications under an open-source license to the public, and the office suite StarOffice which was released by Sun Microsystems in October 2000 as OpenOffice.org (later LibreOffice).

[...]that no further patches to the title would be forthcoming. The community was predictably upset. Instead of giving up on the game, users decided that if Activision wasn't going to fix the bugs, they would. They wanted to save the game by getting Activision to open the source so it could be kept alive beyond the point where Activision lost interest. With some help from members of the development team that were active on fan forums, they were eventually able to convince Activision to release Call to Power II's source code in October of 2003.

The release of the source code came in response to the enthusiasm of Allegiance's small-but-dedicated fanbase. Microsoft's Joel Dehlin commented that the development team has "been amazed at the level to which some of the Allegiance fans have remained hard-core. We’re astounded at the progress that has been made at creating new factions, hosting new servers, replacing authentication, etc. It seems that Allegiance hasn’t really died. With that in mind, we’re releasing the Allegiance source code to the community."
