Almost any mark that is capable of graphic representation can be registered as a trademark. A trademark has an important function of differentiating your goods or services from that of another trader.
You can register a word mark, a logo mark, a slogan or a container shape.
Example: NIKE is a word mark
The Nike Swoosh is a logo

Example: The hour glass shape of the Coca-Cola
Bottle is a container shape

Consumers rely on companies that have a solid reputation and respond to logos and slogans of those companies. Consumers can trust that any location, product, or service bearing your trademarked material is legitimate; your trade mark serves as your badge of origin.
So if you plan on making it big MAKE YOUR MARK now, it’s a small step to a secure future.
