Advertising format refers to the dimensions, technical characteristics, and form that an advertising message takes on a given medium or platform. Each type of media (print, television, billboards, digital) offers specific formats, defined by elements such as size, duration, technology used, and file type. These formats are often standardized or adapted to the specific characteristics of the medium, and their choice depends on the campaign objectives, the target audience, and the distribution channel. The format also influences the potential impact on the audience and the cost of advertising space.
