Definitely western focused, i.e just Europe and the United States.
I learned a lot of artists I did not previously know. I wish he included Wyland and Thomas Kincaide in the modern artists. Their art may stand the test of time better than those chosen.
As others stated, if you want to see the art, expect to spend a lot of time on Google.
