Final answer:
DHL's failure in the U.S. market was largely due to its inability to compete with UPS and FedEx, underestimating their dominance, and not prioritizing retail as a key sector.
Step-by-step explanation:
Why did DHL fail in the U.S. market? The failure of DHL in the U.S. market can mainly be attributed to its inability to compete with well-entrenched competitors like UPS and FedEx. These companies had a dominant presence and brand recognition in the United States, which DHL underestimated. Also, DHL did not prioritize the retail sector as an important customer base, thereby missing out on significant market opportunities. As the retail sector expanded, companies that were able to effectively manage their sales teams and protect their brand image gained national recognition and succeeded, whereas DHL's strategy did not align well with this trend, contributing to their failure.
