Few sellers are a sign of oligopoly. In an oligopolistic market, each vendor provides the majority of the goods that are sold there.
Additionally, oligopolistic industries have a low number of enterprises because it is expensive to establish a business in them.
Large-scale businesses like automakers and airlines are examples of oligopolistic industry players.

Monopolies are at the other extreme of the spectrum from perfect competition in terms of the quantity and intensity of sellers.
There are many little businesses in a market with perfect competition, but none of them can control prices; they all simply accept the market price established by supply and demand.
However, with a monopoly, there is just one seller in the market. The market doesn't necessarily have to be a whole country; it might be a specific geographic area, such as a city or a region.
Public utilities like gas and electricity providers are examples of monopolies.
