In the 19th and early 20th centuries, "Improvements in transportation, communication, and photography made people naturally curious about other places."
Furthermore, "people had readily consumed photographers' images of distant lands, so when the amateurs were able to shoot their own images, they were more than ready.
The smiling faces of family members in front of scenic locations or landmarks became trademarks for the budding amateur. And as these landmarks became well known, more people visited them and they became tourist destinations. The more destinations there were, the more they photographed and included in the family album."
