How did conglomerates and franchises evolve in the post war economy?

In the post-war economy, conglomerates emerged as companies diversified their investments across various industries to mitigate risks and capitalize on growth opportunities, particularly as consumer demand surged. Simultaneously, franchises gained popularity as a business model, allowing brands to expand rapidly by leveraging local entrepreneurs while maintaining brand consistency. This evolution was driven by increased consumer spending, technological advancements, and the desire for standardized products and services. Together, these trends reflected a shift towards larger, more integrated business structures in a rapidly changing economic landscape.
