As a consumer, you are faced with ads for products on everything from billboards to bus stops to websites. Companies spend millions of dollars a year promoting their brands. They are attempting to get you to identify with and to purchase their products.
A logo is a graphic used to represent the face of a product or company. It is a strong marketing tool when used correctly. How can a logo attract attention and leave a positive impression? The logo needs to be easily recognizable, memorable, and visually appealing to the target audience. This means that when a consumer sees the logo, the consumer knows the product. The company hopes that consumers feel they are dealing with a reputable company.
Some companies have done a great job at marketing their products and logos. Consumers can identify the company and its logo just by the shape of the product alone. Can you identify the logos or the companies that produce the following products?

Now think back to the product you identified purchasing in the Unit 1 Introduction. Was there a logo on the product or on its packaging? What did this logo look like?
A logo can be simple or complex, colourful or plain, large or small. What makes one design more visually appealing than another? It depends on many factors, including the type and size of the product and its packaging. For example, a logo on a can of pop can be larger and more complex than a logo on a pencil.
