Answer:
Reverse Adoption theory
Explanation:
According to The Reverse Adoption theory (also known as The Trickle-Up theory), particular styles that began on the streets, among the lower socio-economic class, can get picked up by designers and then those who belong to the upper-class. Since the 1960s, manufacturers and retailers started paying more attention to the people on the street and their styles, looking for inspiration and ideas. Some of those ideas eventually reached the market.
For example, T-shirts were primarily worn by workmen and men in the military as the most practical choice of clothing. They became popular among the working class and eventually in the fashion industry as well. The punk subculture followed a similar path.

While cool jazz preferred a light timbre, hard bop preferred a sound that was heavy, dark and impassioned. The saxophone of choice was tenor which replaced the alto and drummers played in a more assertive style.
The show was called Facts of Life.
