The next major advance came in 1982, when Sims put metal edges on his snowboard so it could be used in a wider variety of snow conditions. He went on to improve and expand the sport over the years, introducing new snowboarding styles, bindings and designs.
Commodity money is a form of money with an intrinsic value. Some of the best examples of commodity money are silver and gold coins. Currency(cash) or banknotes do not have intrinsic value and are virtually worthless in itself. It only has value because society views it as a unit of exchange. This type of currency is called fiat money.
By definition, a commodity product lacks a unique selling point. In an IT context, the term usually differentiates typical consumer products from specialized or high-performance products. A commodity, in this context, is a low-end but functional product without distinctive features. A commodity computer, for example, is a standard-issue PC that is widely available for purchase. As technologies and markets for a given product mature, it is more likely to be considered a commodity, at least in its more basic implementations.
