Here is a video on Business Insider that explains the secret of these four. 

Scott Galloway, professor of marketing at NYU Stern and the author of “The Four: The Hidden DNA of Amazon, Apple, Facebook, and Google” shows how some of the biggest successes in tech have also had major public failures. He explains why failure is an important aspect of success. Following is a transcript of the video.
