Though Semiotics can be defined, I feel like it is an extremely broad concept to understand and to fully cover. What it means to me, is what brand I instantly think of when I hear of a particular product, or what brand I associate with specific images or places. Semiotics to me means relativity to a product, synonymy with a brand or lifestyle.
One example of such symbolism is Disneyland representing childhood and happiness. Invent something that children adore and their parents will happily pay you a fortune. The entire Disney brand is synonymous with children, innocence, and bliss.
Another example of symbolism is perfume with romance. Apparently if you smell like Ralph Lauren, you will have a handsome man frolicking with you in a field. This relation with smelling good leading to a romantic relationship is an example of semiotics in the works, convincing the masses that smelling good = landing a stud.
This video commercial is an example of Smirnoff being the alcohol of choice in representing the party lifestyle. Smirnoff indicates a good time, women, and being the life of the party.
