Monopoly (economics)
From Tardis Wiki, the free Doctor Who reference
A monopoly was the control of a resource by a single entity. Lady Adrasta had a monopoly on Chloris' metal. The benefits she reaped from this made her unwilling to agree to Erato's proposed trade agreement, despite its popularity with her subjects, leading her to imprison the ambassador. (TV: The Creature from the Pit) Josiah W. Dogbolter once described the Time Lord's control over time travel as a monopoly. (COMIC: Time Bomb!)
