Too Long; Didn't Read
The internet as we know it today is centralized. Centralization refers to a structure where one or a small number of entities control an entire network. At the moment, a small number of very powerful technology companies exert the most control over the internet. These few companies are known as the FAANGs (Facebook, Apple, Amazon, Netflix, and Google, with other companies like Microsoft and Twitter also in the oligopoly). These companies are powerful enough to set the terms for industry standards. Smaller entities follow suit and use similar methods of operation. In this way, the current internet can be described as centralized.
