Cameras have existed for considerably longer than 100 years; we have surviving photographs from the American Civil War, in the 1860's, which was over 150 years ago. Of course, those cameras were very different from modern cameras, but they did work.

Some sports that were around 100 years ago but do not exist today include tug of war as an Olympic sport, singlestick fencing, and roque (a variation of croquet). These sports have either faded in popularity or have been replaced by more modern alternatives.
Computers, iPhones, and flat screen televisions are all inventions that didn't exist 100 years ago. Cell phones and smart appliances are a few more.
The answer to this one is...... that everyone uses cameras (even people who were born donkey's years ago)
