Sense of Space - Research - 'Art Cinema: An introduction'

For part of my research I read the chapter on sound in the book; Art cinema: An introduction 2010 9th ed. Whilst this isn't directly related as we are not creating sounds for the cinema but instead a soley sound output, it did however hold some interesting ideas. I find it interesting that people have come to expect great quality hyper-real Dolby surround sound within the cinema and in recent years have invested in home cinema audio kits so that they can bring the cinema experience into their living room. Does this mean that there is a gap in the market for sound only productions, for the growing interest in sound design.
