Scott Galloway, professor of Marketing and Brand Strategy at NYU Stern, recently delivered a presentation on the Gang of Four: Apple, Amazon, Facebook, and Google. These dominant companies are also often referred to as the “Four Horsemen.”

The video is about 16 minutes long and I would highly recommend that you give it a watch.

It’ll be like drinking from a firehose, but there are so many fascinating takeaways. You’ll also quickly discover how far reaching the societal impacts of these companies have been and will likely be in the future.
