A logo is a graphic mark or emblem commonly used by commercial enterprises, organizations and even individuals to aid and promote instant public recognition. Logo design is an important component for a web designer. Logos are used as brand identification in advertising, business cards and letterhead. 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 and CocaCola written in flowing red script.
