I was born in the 60's .... warning "When I was a youngun' " story ahead.
I remember when VCRs first came out, and people were buying or renting movies. I still remember the feeling of awe at holding a tape of an actual movie that I remember clearing my schedule to watch because it was finally going to air on tv, and having the ability to not only watch it once, but as many times as I could manage in the alotted rental time.
I think I watched "The Wizard of Oz" about 5 times in one rental period, and I was kind and rewound

I got to relive childhood nostalgia.
Now these things are everywhere with one mouse click.... there are many people who were born only in the past 25 years who just don't have that kind of perspective to draw from. I told my teenage son this and he thought I must have been underprivileged as a child... but no, this was normal.
