We learned about stages of Globalization.

•Globalization 1.0 (from 1492 to 1800)

eg. Christopher Columbus

•Globalization 2.0 (from 1800 to 2000)

eg. in first half. Railroads build.

      second half. Notebooks and Smartphones.

The global economy began appearing during this era.

•Globalization 3.0 (from 2000 to the present)

Around the year 2000, we entered Globalization 3.0, which was driven by the convergence of ten forces that Friedman calls “flatteners”.

-In era 3.0, the global, Web-based platform has emerged.
