For the purposes of this question, let's say I am a Sculpture Artist whose work is based on various Sports Stadiums and Teams around the World. Each piece of Art will be exclusively available via an eCommerce website, and marketed on a Global level.
After perusing the Internet, many articles (and Forum responses) have suggested that I should focus my research on the Art Market as a whole.
My first question would be 'why'? Whilst I would be looking to participate in the Art Market, wouldn't such research simply be too broad and give historical figures from the past that may not be useful for future projections?
Alternatively, wouldn't it be more useful to obtain figures of various Sports Fan Bases as these would be potential customers or have I misunderstood the purpose of Market Research; in particular Market Sizing?
