My husband and I have this discussion often: how much technology has changed in the last 30 years. Oh, it's changed tremendously over 100 years, but I think really, the biggest, most dramatic changes have happened in the last 30 and less. The most relevant changes being cost and size. Before 30 years ago, bigger was better, and improvements meant getting bigger, not smaller, but that seemed to reverse a lot in the 80s. Cell phones started out being big clunky things you carried with a shoulder strap and a charger,
camcorders had to be carried on your shoulder when used, and were as big looking as most commercial movie cameras today. The above also cost about 20 times as much as they do now. Our first camcorder was huge, used bulky VHS tapes, and cost several thousand dollars. It was the earliest version, highest-tech of its time: real state of the art stuff, that would now make you laugh as you looked at the viewing screen on your hand-held camera with computer link and SD card storage that cost a couple hundred dollars.
