Step-by-step explanation:
The evolution of marketing in the U.S. can be divided into four eras: the Production Era, the Sales Era, the Marketing Era, and the Relationship Era.
In the Production Era, which lasted until the early 20th century, businesses focused on producing goods efficiently and did not engage in extensive marketing.
In the Sales Era, which emerged in the early 20th century, businesses began to emphasize selling and promotional activities to drive sales.
The Marketing Era started in the 1950s and shifted the focus towards understanding customer needs and creating products and marketing campaigns tailored to those needs.
The Relationship Era, which began in the 1990s, emphasizes building long-term relationships with customers through personalized marketing, customer service, and loyalty programs.
