A number things the Industrial Revolution made possible:
Rapid Transport, people could travel vast distances quickly, this enabled arts to experience different cultures, and bring new art to regions.
Mass Publication of work: Allowed vast printing of arts around the world, which meant artists could see the work of other artists, and art from around the world.
Paint in Tubes: Artists are free of the studio, able to go out in nature and paint first hand.
Open a New Public, a new middle class began to buy art, with a new set of aesthetics.
Create new Inequality and Suffering that some Art revolted against. ]
