A logo is a graphical element (ideogram, symbol, emblem, icon, sign) that, together with its logotype (a uniquely set and arranged typeface) form a trademark or commercial brand. Typically, a logo’s design is for immediate recognition. The logo is one aspect of a company’s commercial brand, or economic entity, and its shapes, colors, fonts, and images usually are different from others in a similar market. Logos are also used to identify organizations and other non-commercial entities.
Today there are many corporations, products, services, agencies and other entities using an ideogram (sign, icon) or an emblem (symbol) or a combination of sign and emblem as a logo. As a result, only a few of the thousands of ideograms people see are recognized without a name. It is sensible to use an ideogram as a logo, even with the name, if people will not duly identify it.
