I, too, can remember the slide shows (and, perhaps to a lesser extent the 8mm home movies) with friends and relatives, up to maybe about 20 years ago. Often they formed a pleasant social evening with a few drinks and nibbles.

It's unusual now to see any holiday pics, except maybe the odd on-or-two on a tiny screen on the back of a digital camera, while information on any subject is instantly available on the web. And I know of no-one who puts their digital prints (other than family shots) in frames or albums.
