Duopoly Definition and Explanation

Duopoly definition comes from its prefix, “du” – meaning two, so –

it is a situation where two companies control a particular sector of the economy.

Furthermore, to understand duopoly definition, just remember the concept of monopoly, it is when an economic sector is controlled by one company. Their only difference is that “mono” means one.
