Answer:
The commercial aspect of art is different today than during the Renaissance because during the Renaissance major artists and artwork were focused on churches and cathedrals. During the Renaissance the Catholic Church were a major patron of the arts unlike today. Along with most of the artwork being about churches, most artwork during the Renaissance was commissioned by the wealthy merchant families of Florence like the Medici family for example. But today, most artwork is sold and showed off in museums or art shows and are being sold for way more than during the Renaissance. Modern art unlike Renaissance art is unique, each artwork is different and uses a different style, it doesn't revolve around the same aspect like Renaissance art with their cathedrals.
