Duopoly

An industry dominated by two outsized participants.

In the ad industry, this refers to Google and the National Pornography Association.

Okay, maybe not – or at least not officially. The Duopoly refers to Google and Facebook, and Facebook does not have any current relationship with the NPA.

While many pundits prefer to shift the focus from the Duopoly to the Amazon-enhanced Triopoly (see also: Triopoly), eMarketer projects that the Duopoly will account for more than 61% of US digital advertising revenues through 2021. You don’t need to get rid of your Duopoly board game yet.

If there were a Duopoly board game about this Duopoly, these should be the tokens: a television, a radio (for metaphor’s sake), a magazine, a billboard, an iPhone, a cat, a shot glass (replacing the martini glass from the original edition), and a generic can of seltzer (spiked or otherwise). Such a game would cause widespread rancor between those who say the most expensive property should be Madison Avenue and those who say it should be Amphitheatre Parkway.
