Oligpoly is a market dominated by a small number of large sellers (oligopolists).
The steel industry would be the best example of an oligopoly.
A unique feature of an oligopolistic industry is: mutual interdependence , few large producers that produce similar but slightly different products.
It is called strophic form. Hope this helps!!
