Final answer:
A company that defines its markets narrowly and strives for global depth rather than breadth uses the concentrated global targeting strategy.
Step-by-step explanation:
The global targeting strategy that is used by a company that defines its markets narrowly and strives for global depth rather than breadth is the concentrated strategy. With this strategy, the company focuses its resources and efforts on a specific segment of the global market.
For example, a luxury car company may target high-net-worth individuals in major cities around the world. By concentrating on this niche market, the company can tailor its products and marketing messages to meet the specific needs and preferences of its target customers.
