Indeed, visual culture seems to be an art in the context. It has touched me because art also may not be displayed. But if it is, then we have different stages and depth of incorporation the work of art into the society narrative.

Also, we have an example of the pop art movement that reflected on advertisement.

About the last section, I would notice that, for instance, French posters from the Art Nouveau Era are already considered to be an art (Mucha, Toulouse-Lautrec). Were they a commercial content in its purest form? I think, they were an advertisement someday, but they did include the aesthetics. The question is how it correlates now in TV ads between the desire of selling the commodity and visual part of it.
