I think you forgot to put the choices to your question so I'm going to answer it the best I can and hope you find what you are looking for.
an artist can post their artwork on the internet and gain a wider following and will be able to find work easier than if they just showed to galleries and art shows. They can use modern technology to attract potential print buyers and buyers interested in a commision, making it easier for an artist to make a living off of their artwork without a sponsor.
I hope this helps you!
