Is there a difference between audiences and markets? There certainly is.
While the market refers to a public space where I go to leave my breadcrumbs, the audience relates to those in the said market who influence my decision-making in shaping my media content. The audience thus shapes the market, and because there is an audience, I can see what trends are ongoing to see how I can fit myself without losing my Linaness in the market and still attract the audience.
In a way, I would always be part of the audience in a market because I will constantly observe any changes, feeding into the trends and reacting to those changes.
