variety

variety
A particular good differentiated by specification or brand name from other similar goods.
The existence of a large number of varieties in sense 1. Variety is good for consumers partly because their exact requirements differ, so that a wide choice gives more chance that they can obtain goods which are a good approximation to their ideal specification, and partly because individual consumers want the ability to vary their consumption over time. A large proportion of the real gains from economic growth and integration derives from increases in the variety of products available.
