The document summarizes Thomas Friedman's book "The World is Flat" which discusses three phases of globalization and ten factors that have flattened the global economic playing field. Globalization 1.0 from 1492-1800 shrank the world from large to medium as countries globalized. Globalization 2.0 from 1800-2000 shrank the world from medium to small as companies globalized. Globalization 3.0 from 2000 onward shrank the world from small to tiny as individuals can collaborate and compete globally through technologies like the internet.
