Explain the concept of cultural convergence and provide an example.

Cultural convergence is a concept that describes the blending and merging of different cultural aspects or practices over time. It occurs when diverse cultures come into contact with each other and, as a result of globalization, trade, or communication, they adopt or incorporate certain elements of each other's cultures.

An example of cultural convergence is the global popularity of fast-food chains such as McDonald's. The concept of fast food, initially developed in the United States, has spread to various parts of the world. In many countries, local cuisines have incorporated fast-food practices, leading to the emergence of unique fusion dishes that combine local flavors with fast-food convenience. For instance, McDonald's Korean-style bulgogi burger caters to the taste preferences of South Korean consumers while still maintaining its fast-food identity. This example illustrates how cultural convergence can result in the adaptation and integration of cultural elements from various societies, leading to new cultural expressions.
