A logo is a graphic mark or emblem commonly used by commercial enterprises, organizations and even individuals to aid and promote instant public recognition. Logos are either purely graphic or are composed of the name of the organization. An example of an abstract mark is the blue octagon representing Chase Bank, while an example of a representational mark is the “everyman” icon of PBS. Examples of well-known logotypes are the striped IBM design, Mobil written in blue with a red and CocaCola written in flowing red script.
