I don't know how I survived in the 70s and 80s when if you missed a show, that was tough luck until summer when they did re-runs. We did eventually get a VCR but that was usually reserved for very important shows because it was such a pain to use.
I remember when DVRs were brandy new and a bit pricy, friends had one and I thought this is the best. thing. ever.! As soon as I could, I got one.
I love mine. Yet I think back to the pre-cable days, when you watched the holiday specials the once-a-year they were one, and if you missed it, too bad, and it really wasn't that big a deal!
Now? if you miss something, all you do is look to see when its on again, nad record.
