How has globalization impacted the diversity of world cultures?

"Distinct societies of the world are being overrun by globally available goods, media, ideas, and institutions. The more cultural homogeneity that is attained, the easier it is for businesses to sell their products globally. As the world's cultures move toward one main culture, some unique ethnic aspects disappear. Some cultures perceive this as a threat - the threat of dominant, industrialized cultures overtaking and supplanting indigenous cultures."
