Final answer:
Television becoming increasingly popular is not an example of how technology transformed post-World War I America since TV's popularity rose in the 1950s. Instead, radio and the Model T Ford were significant technological developments that shaped the 1920s.
Step-by-step explanation:
Technology played a transformative role in post-World War I America in various ways, but the option that does not represent this period is that television became increasingly popular. While radio technology, automobile ownership, and magazine circulation saw significant growth during this era, television did not become widely popular until the post-World War II period, specifically in the 1950s. During the 1920s, however, radio became a central part of American life and culture, with commercial radio broadcasts creating a sense of a unified mass culture. The automobile, particularly the Model T Ford, revolutionized personal transportation, making car ownership accessible to the middle-class American. The expansion of magazine circulation also reflected the technological advancements in the postal service and a growing consumer culture.
