What do Docker containers have to do with Web browsers?
Web browsers provide easy access to the digitized collective knowledge of the human race, political rants, serious applications and even silly kittens.

Prior to browsers, networked applications existed. Mostly, they were client-server two-tier applications, but they were quite popular in business, and many home personal computer users had such applications.
