Final answer:
Amazon Echo's adaptation to different regions is an example of a product adaptation strategy, which changes products to suit local preferences influenced by cultural integration and regional characteristics.
Step-by-step explanation:
When Amazon Echo's Alexa and speakers adapt to fit the nation and region of the user, this is an example of a product adaptation strategy. This strategy involves changing a product to meet local cultural, legal, or consumer preference differences in the different markets that they operate in. Cultural integration is significant in this context, as patterns of regional ethnic heritage influence various aspects of local markets, including regional agro-economics, and technology products like Amazon Echo must adapt accordingly.
