The internet pervades human existence so thoroughly now that it can be hard to remember how recently life was mainly analog. When was the point of no return? Maybe around 2006. In July of that year, a microblogging platform called Twitter debuted for the public. In September, Facebook launched a new feature called “News Feed” and opened membership to all comers, where before you had to be part of a college or school network to join. In 2006, YouTube was barely a year old. The first iPhones didn’t go on sale until 2007.
