Every day, there are 770 million Cokes consumed, which means that there are 770 million purchasing decisions made each day regarding the product. To support those decisions, the company must constantly reinvest in its marketing links to its customers. As a result, a high level of creativity must go into everything the company does, from cause-related campaigns - Coca-Cola and its sponsorship of the Olympic Village in Atlanta, for example - to new catch phrases, commercials, marketing slogans, advertising campaigns and promotional tie-ins.

The creative process is different from the traditional production and work-flow process. It is not so linear.

If you are at Coca-Cola, the creative challenge is one of maintaining - rather than creating - a tremendous level of consumption for your products.
