The movement from camera film to digital cameras was a largely unnoticed revolution which took place within the last decade.

In industry, that may be so (I seem to recall one of the Star Wars prequels being the first feature movie done entirely with digital cameras). For end-user video cameras (handicams, or whatnot), we've been storing to magnetic tape for a good bit longer though.

Being digital doesn't mean using solid state storage. Magnetic tape is probably still the most used medium for digital video cameras. For example, Betacam SX is still used.

On a recent vacation I was photographing my nieces and nephew making funny faces. After the first shots they ran up behind me, looked at the back of the camera, and said, "Can I see?" They gave me bewildered looks when I told them it was a film camera and they'd have to wait a few weeks.

Ha! I took a Hungarian class with my daughter a couple of years ago; I think she was 8, which is why she needed me to sit in with her, given it was a college class at IU. (I should explain that her mother is Hungarian, and so this was more in the way of language practice and grammar instruction, not that my daughter is a super-genius. Although, of course, she is.)

Anyway, one of the dialog exercises was to talk about hobbies, and one of the hobbies was record collections, with a picture. She had absolutely no idea what the picture was supposed to be, until I explained to her that they were like CDs. The other students in the class exploded with laughter.

For that matter it won't be long before children have no idea what a music CD is, if we're not there already.

My younger child is 11; he hasn't had much interaction with physical storage media for music.

I was in the same boat. My son found an old disposable camera in a drawer, and I couldn't find a decent way to explain it to him with out the WTF? look on his face.

One of my nieces was photographed by her grandmother with a film camera, and immediately ran to her, expecting to see the picture on the back of the camera. On learning that wasn't possible, she exclaimed "oh, it's not working".

I recently had to explain to a class of college students what a LaserDisc was. It turned out, luckily, that one of the students also knew...

My god - that's a blast from the past. I actually credit the fact I ended up studying history to the 'Doomsday disc' the produced in the UK... would love to see a copy now. Do people still have the hardware knocking around?

The student who knew grew up in a household full of 'em. Videophiles find advantages in LaserDiscs over DVD: http://www.starlaser.com/dvd-lasr.htm and http://en.wikipedia.org/wiki/Laserdisc#Comparison_with_DVD. Jacket art and possible increased quality due to uncompressed video are cited. I didn't know LaserDisc was an analog format! LaserDisc has some of the grooviness of the 8-track, if not the deep catalog of the LP.
