DMA (Designated Market Area)

A Designated Market Area (DMA) is a geographic region used by media and advertising companies to define a specific TV or radio market. It helps identify where viewers or listeners are located, so advertisers can target audiences effectively. DMAs are based on television viewing patterns and population data, and they often cover large areas that can include multiple cities and suburbs. This system ensures that advertising efforts reach the intended local or regional audience, making campaigns more efficient and relevant to specific communities.
