a symbol or other small design adopted by an organization to identify its products, uniform, vehicles, etc. : the Olympic logo was emblazoned across the tracksuits.
Logo design is an important area of graphic design, and one of the most difficult to perfect. The logo (ideogram) is the image embodying an organization. Because logos are meant to represent companies' brands or corporate identities and foster their immediate customer recognition, it is counterproductive to frequently redesign logos.
Logo design is all around us. To the general public, logos serve as an instant reminder of a company or a product; to the client they're the point of recognition on which their branding hangs; and to us designers they represent the challenge of incorporating our clients' ideologies into one single graphic.
