Product support is a service provided by many retailers of various products, primarily electronics, that provides the end-user with a resource for information regarding the product, and help if the product should malfunction. Product-support information can be found in most manuals for products via a phone number, web site address, or physical location.
The Internet has allowed for a new form of product support to develop. Some online communities have developed to give support where manufacturer support is lacking.
