What did original digital cameras have that was different then current ones that flash?

A professor of mine once told me that the earlier cameras did not always flash. Because of privacy issues the technology was changed so cameras would flash. And people would know when their picture was being taken. Does anyone know what the difference was?
Ditto, this is a twisted tale and a total lie.
It might be something confused with something else. For example some camera phones make a sound when you take a photo that cannot be turned off to make it harder for peeping tom types.
but flashing to let you know that a photo is being taken is just plain dumb because all cameras that have a flash have the option to turn the flash off. Old cameras and new. your professor has it wrong.

Whomever told you that misled you.
Digital cameras do NOT always flash. I have two now and have had several others in the past. The flash only goes off if the camera detects a low light situation.
Digital cameras EAT batteries. That’s one of their biggest downfalls. If the flash went off every time you took a picture, need it or not, then the batteries would be dead even sooner than they already are.
I can’t imagine a "professor" telling you a story like that.
Other than some technological advances like faster shutter speeds, longer battery life, smaller size, larger mega pixels and lower costs, there isn’t much "basic" difference between the digital cameras today and 15 years ago.

Your professor is just giving you crap. Flashes have been on cameras since long before digital cameras existed.
Flashes have nothing at all to do with privacy. They are used to add extra light when it is needed. In low light situations if you didn’t have a flash you would need to have a long exposure. Long exposures are fine if your subject and camera are perfectly still. They are not so good when photographing moving objects (people, animals etc.) or when hand holding the camera.
