Businesses, groups and individuals use trademarks, logos and symbols to generate brand awareness in public forums, in order to make it easier for people to recognize a product, business or individual by simply associating them with their trademark. Symbols have been used for thousands of years all around the world, so for an emblem to have made it onto this most recognizable list, it would have to be associated with people in more than one country.
The most successful logos are best described as being ones where the actual sign doesn't even need to be specifically noticed, because when people see a product or group they will instantly associate that product or group with their trademark or symbol within their own minds. However, for an emblem to be considered as one of the most recognizable marks, it would have to be easily identifiable by people the world over. While there are millions of symbols being used worldwide, only a handful of them can be considered truly universal and recognizable by individuals from around the world.
