Discs in the mail? I remember when the mail WAS the internet! If you wanted to talk to somebody it was either make an expensive long-distance phone call or send a letter and wait! Taking photos was a costly and tedious process: You had your camera, which you'd load with film. If you wanted to take pictures indoors you had to buy flash cubes. You'd have to wait until you used all the shots on a roll of film, then you'd send it off in the mail to be developed because getting it done locally was almost a car payment. Once the pics came back three weeks later you'd look at them, only to discover that 90% of the shots were no good because they were overexposed, blurry, too dark, or, even sometimes double exposed (Taking two pics on the same frame of film).
And as for Blockbuster, I remember going to a video rental store and hoping like hell the one or two copies of the latest release that they had (on Betamax, at that) weren't already rented out!
Oh yes. I was there three thousand years ago.
