Homogenization in globalization refers to the process of reducing cultural diversity through the popularization and diffusion of cultural products and practices. This process can impact national identity and culture, which would be "eroded by the impact of global cultural industries and multinational media". Homogenization can take place in various ways, such as the increasing similarity of cultures in a way that makes them homogenous or unified. Some scholars argue that homogenization is not necessarily a bad thing and that the benefits of homogenization may outweigh the goods of cultural diversity. However, generally, homogenization is viewed negatively as it leads to the reduction in cultural diversity.

Homogenization can occur in various fields, such as language, ideologies, cultural arts, architecture, food, and fashion. For example, the transitions of countries to international languages such as English, French, or Arabic allow for homogenization as different cultures use the same language, making them become more similar to each other. Cultural homogenization, as well as hybridization, takes place since the cultures of periphery and semi-periphery countries are susceptible to changes, as adaptations towards cultures of developed countries give people a sense of improvement.

While homogenization refers to the increasing similarity of cultures in a way that makes them homogenous or unified, others argue that globalization leads to cultural hybridization. Cultural hybridization refers to the interaction between local cultures and global ones, which lead to the transformation of mainstream cultures. Heterogenization is another concept that can take place in a local context, referring to the increased diversity within a territory, or in a global context, referring to increased transnational differentiation.

In conclusion, homogenization in globalization refers to the process of reducing cultural diversity through the popularization and diffusion of cultural products and practices. While some scholars argue that homogenization is not necessarily a bad thing, generally, it is viewed negatively as it leads to the reduction in cultural diversity. Homogenization can occur in various fields, such as language, ideologies, cultural arts, architecture, food, and fashion.
