Definition

The actual purchase of advertising space or time, where agencies negotiate with publishers to secure placements. It's like buying real estate, except the property disappears after 30 seconds and costs are measured in CPM instead of square footage.

Example Usage

Our media buy for the holiday campaign included premium placements on three major networks and a takeover of Times Square.

Origin

Traditional advertising terminology from the Mad Men era of the 1960s

Fun Fact

In traditional media, buyers would literally negotiate over martinis at lunch; now it's done algorithmically in milliseconds by computers that definitely aren't drinking.
