Pretty amazing glimpse into the past... You could be right about the timing; it IS a major technological change.
There were about 200K people with Internet access when I got my first email/online account. It was "weird tech" for deep nerds and creepy pedophile stalkers, in the eyes of most. That was 1993. We hit a billion users (i'd consider that "mass adoption") in December 2005... so that was 12 years.
"We hit a billion users (i'd consider that "mass adoption") in December 2005... so that was 12 years." You are absolutely right. People forget that actually "mass adoption" of the Internet really only occured in 2005. Thanks for the comment. I hope everyone reads it. Stephen
