Hot & Cold Media

I'm still having a slightly difficult time understanding hot and cool media but from what i gather, hot media is specific to things that don't require a lot if any, audience participation. These are mediums such as movies, and records. Cool media refers to media such as tv and radio where not all of the information is present. I think this is an important factor for an artist, especially a visual artist, for how they are going to publicize their work. Who do you want to see it? Who is your target audience? If you remember these terms and how they affect the way art and media flow through our culture you can have a better understanding for how to present it to the public. This is my practical application anyway.
