Early investors in some of the biggest companies in the world, like Facebook, Amazon, Walmart, or Netflix, have seen their fortunes greatly magnified over the years.

Business Insider took a look at historical split- and dividend-adjusted price data from Yahoo Finance for 22 corporations that have become household names, and found what a $1,000 investment made back in the day would be worth as of their closing prices on July 3, 2018.

For companies that held their initial public offering or came into being after 1980, we used their IPO date as the starting point, and for older companies, we assumed an investment in early 1980.
