Go to any event and observe dressed up folks taking selfies. Or folks asking someone else to take a picture for them. Also observe how younger people are examining the background- i.e. the photo frame. The purpose of those photos is not to take a print and make an album. But to post on instagram!
The TJX group (including brands like TJMax, Marshalls, HomeGoods etc.) and Costco seem to be always crowded. And when you look at long checkout lines you know they must be doing something right in the digital age.
