Globalism refers to the integration of companies, resources, or markets from different areas of the world. With the innovations in communication and transportation that were realized in the last century, companies in one country can utilize other countries around the world in the execution of their operations. A company can have offices in the United States, manufacturing plants in Asia, customer service centers in Europe, and stores throughout the world. Globalism is a word used to define this economic synthesis.
Diffusion is a very similar word but is used to define the cultural sharing that occurs when groups from different areas of the world are joined. Cultural diffusion commonly occurs as a result of globalism. An example of cultural diffusion is how rap music originated in the United States, but can now be found in all parts of the world. Rap music is now recorded in dozens of different languages in all parts of the world.
