I’ve used computers since the early 1980’s, and accessed the internet or its precursors at the end of that decade, mostly through BITNET. Listservs were the forerunners of forums like this one, and people could connect to each other via e-mail as well. Chat was in its infancy then, and that was a rather revolutionary concept, to unite people so widespread in such an instant manner. I didn’t use browsers though, until a bit later, when I took an introductory course on Netscape for professional development.
Although I had a computer in junior high school, I used typewriters for all my papers through high school, and it wasn’t until I entered college that I really started to use word processors. As @tedd mentions, floppy disks were the storage medium back then, and my first floppies were the 8-inchers. These were soon replaced by the 5¼ inch disks, and then the 3½ inch ones (which I still have several of… I really need to make time and sit down and transfer whatever the hell’s on them off onto the hard drive and determine if I have anything worth keeping!).
As for your questions, yes, it’s changed society a LOT. Think about the use of Twitter recently during the events in the Middle East last year, for example. Phone books are dying, because you can just Google a person. Even the word “google” itself has changed. Prior to the 1990’s, you’d either get a blank stare or someone would think you’d be talking about Barney Google.
Libraries used to have physical card catalogs; now it’s all computerized. In the days when I had money to travel, a stop at Triple-A was de rigueur; now I can use Google Maps (or Mapquest, although I haven’t used it in about ten years). People used to buy records, 8-tracks, and tapes; now people use MP3 and file-sharing to access music; it’s changed the recording industry so much the RIAA, among other powers-that-be, has reacted vociferously to the potential and actual loss of revenue. In many towns and cities, the red-light district had at least a few dirty bookstores. The advent of videotape (and then DVDs) and computers has brought porn into the home, so that now the bookstores are dwindling (there’s other factors involved, sure, but the internet/technology has really affected this). People are now reading books, checking their e-mail, and doing other daily activities on tablets, smartphones, and other computerized devices.
Even medicine has been affected by the advent of the internet. Sure, you may still go to the doctor, but how many of you check sites like WebMD first, and try to second-guess your physician?
So yes, I think the internet has changed society, for good in some ways, and possibly for worse in others.
As for preferring the days when contact was face-to-face, yes, I think there are a lot of advantages to in-person contact than through the computer, but I also think interacting online has sped the exchange of ideas in positive ways. It’s a double-edged sword, and would take another post to fully discuss, heh.
