Fashion is an industry where hundreds of individual designers, some with the backing of megacorps and some without, try to meet popular interest (or to lead it), with production times measured in weeks to months, and with seasonal variation.
There is no "fashion cabal" where designers get together for drinks and to anoint "cerulean blue" as the color of 2023 and then pull their customers by the nose ring into purchasing.
(Yes, there is a media-favorite color survey that gets printed every year, and there are some downstream effects of that).
The music industry works similarly. Bands toil for years (or months), doing their thing, and A&R reps from major labels try to predict what they can promote that will be popular enough this year (based on the choices of other promoters in the industry), or next year, to sell in the near term, and yet differentiated enough to have lasting value.
The snack food industry works similarly.
The software industry works similarly.
The political industry works similarly.
