When did the service-based economy began?

The service-based economy began to take shape in the late 20th century, particularly during the 1970s and 1980s, as industrial economies shifted towards services such as finance, healthcare, and technology. This transition was driven by advances in technology, globalization, and changes in consumer preferences. By the early 21st century, many developed countries saw a significant portion of their GDP and employment coming from the service sector, marking a notable departure from traditional manufacturing-driven economies.
