Around 2000 when I was little, Cartoon Network in India used to run various contests for which you'd need to mail in an entry to participate. The problem was that the shipping address would be displayed on the TV maybe for 2-3 secs and I could never get it. After a few tries to memorize, I whipped out my solar camera and prepared for the address to appear again and clicked a picture and got it developed to get the address.

A few years later when I was in high school, everyone used to have the state-of-the-art 0.3MP-1.3MP cameras on their Moto L7 and Nokia 6600. My high school would frequently stick various notices like people's test scores, examination schedules etc. on the walls and those walls would get swarmed and you'd have to stand for minutes in the swarm getting pushed while you found your name on the many sheets of paper that were stuck, or while you copied the exam schedule etc. I'd get to the front of the swarm and channel all my energy into holding my phone steady pointed at the wall and click a picture and later zoom into it to get the information I needed from the comfort of the librar. I'd hear a chorus of 'aaahs' each time I did this when everyone would realize they could do the same.

Realization that you can click pictures of documents these days of course is almost common sense :)
