Development of Essay Question

‘To what extent does visual identity affect the public perception of a product or brand?’ Through my continued research over summer, I have revised my original essay question and have tried to focus on a more specific element of branding and marketing, whilst still keeping potential topics quite open ended. My revised essay question allows me to investigate marketing and branding, as well as it's effects on public perception of a brand- meaning I will have to use a few case studies to back up and re enforce my arguments.
