When I was in 6th grade (~1993), someone's dad came to talk about our class about the "superhighway of information" or the "information highway". It always bugged me that he didn't say "information superhighway".
Does anyone still use "Information Superhighway" anymore? I think most people just say "internet".
However in the 90's that analogy helped many non-technical people understand how to think about the internet. Back then did you have a better analogy?
BTW, as a marketing guy, it always bugs me every time anyone uses the term "marketing" when they mean "advertising". I'm not referring to you/your post but rather a general trend on HN and elsewhere.
