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 (symbols/icons) or are composed of the name of the organization (a logotype or wordmark). 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 (wordmarks) are the striped IBM design, Mobil written in blue with a red “o” and CocaCola written in flowing red script.In the days of hot metal typesetting, a logotype was a uniquely set and arranged typeface or colophon. At the level of mass communication and in common usage a company’s logo is today often synonymous with its trademark or brand.
