Final answer:
In the 1990s, technology sectors emerged as vital economic drivers, reducing reliance on traditional industries like automotive manufacturing. The rise of computer companies and software firms initiated broader economic development and diversified the job market.
Step-by-step explanation:
The development of technology-based industries in the 1990s shifted the economic drivers and helped diversify the revenue streams of many states. This significant change decreased the reliance on traditional industries such as the automotive industry, which had previously been the backbone of the American economy. The influx of computer companies and the establishment of software firms led to the creation of hubs similar to California's Silicon Valley. This growth contributed to a broader economic development across different regions, providing new job opportunities and aiding in the transition from manufacturing-focused economies to more varied and robust economic frameworks.
