Cultural imperialism refers to the dominance of one culture over others, often through media, language, and values. This can happen when a powerful country, like the United States, spreads its culture globally, influencing local traditions and lifestyles. As a result, smaller or less powerful cultures may struggle to maintain their unique identities. This phenomenon can lead to the erosion of local customs and practices, as people adopt the dominant culture's way of life. For instance, the popularity of Hollywood movies and Western music can overshadow traditional art forms, making it challenging for local artists to thrive and be recognized.
