In many domains like cosmic evolution, big history, art history, timelines are segmented in well defined epochs. As changes happen gradually over time, it’s not absolutely necessary to link the dates where one epoch ends and another begins to a precise event. A Web Timeline should reflect the main trends and have a sufficient granularity to cope with the main changes in Web technology. A Web Timeline should take into account that the evolution of the Web is not linear, but exponential and comply to Ray Kurzweil‘s Law of Accelerating Returns.
I was keen to propose in my contribution Divide the Web Timeline in nine epochs, a segmentation from Web 0 (1930 >) to Web 4.0 (<2020). I am not aware that a global and comprehensive timeline division exist already for the Internet or the World Wide Web. If anyone else has already proposed this somewhere, I would be happy to give him credit.
