What is the purpose of a logo?

The primary purpose of a logo is to give a visual identity to a company or brand. A logo is a symbol that companies often use in advertising, stationery and other business materials that allow people to easily recognize the brand and its meaning.

Ideally, people easily correlate a logo with the brand it represents. This correlation improves the ability of a company to emphasize visual elements in its promotional messages. In some cases, logos also carry some significance or meaning about the company's history or its core values. In these situations, the logo also contributes to development of a unified company culture.
