Final answer:
Motown, founded in Detroit in 1959, became the most successful record label in the U.S. by 1965 due to its adoption of Detroit automobile industry-like production techniques, talented artists, and effective marketing strategies.
Step-by-step explanation:
By 1965, Motown will be the most successful record label enterprise in the U.S. Founded by Berry Gordy Jr. in Detroit, Michigan, in 1959, Motown played an essential role in the racial integration of popular music. The label achieved significant success with a series of crossover hits. Motown's business model was informed by the success of Detroit's automobile industry. The record company applied assembly line techniques similar to those of the motor industry to the production of its music. This methodology, alongside a combination of talented artists, distinctive Motown sound, and effective marketing, propelled the label to great heights.
Detroit's history of manufacturing giants such as Ford and General Motors provided a blueprint for success in terms of mass production and competition-fueled innovation. This, combined with the cultural, political, and economic conditions of the time, helped the label to achieve and sustain its status as a leading enterprise, known worldwide for its contributions to music and culture.
