Twenty years after the World Wide Web went live, Aleks Krotoski tracks what it actually became versus what its inventor promised. Tim Berners-Lee appears to restate his original vision of an open frontier owned by no one, and across four episodes Krotoski tests that idea against interviews with Mark Zuckerberg, Bill Gates, Al Gore, Martha Lane Fox, and Stephen Fry. The series moves from the rise of blogs, Wikipedia, and YouTube, through Twitter and YouTube's role in politicizing young activists, into the business history of the dotcom crash and how Google built an advertising engine out of free search, maps, and video. The fourth episode turns to the body and brain, with a University College London experiment measuring how constant web use affects attention and mental load. Krotoski's argument threads through all four hours: the technology's open possibilities keep colliding with old human instincts to control, profit, and consolidate power, and the web that exists now is the residue of that fight rather than the frontier Berners-Lee described.
