It's mind-boggling how the 5 most valuable internet companies have changed over the past 20 years

In 1995, the internet was just about to get started. It was only a year after big internet companies like Yahoo and Netscape were founded.

Fast forward 20 years later, and the web business landscape looks a lot different from back then.

In fact, only 1 out of the 5 most valuable public internet companies from 1995 are still in the top 5 list, according to Mary Meeker's "Internet Trends" report.
