I remember back when they first started getting popular I was at a conference and told a marketing person that we should make one instead of giving folks a long url. The marketing person said "I don't know if we have the budget to register one."
I used to think that this was because the marketing person didn't know how they worked, but now I know that they thought it worked like UPCs.
Shout out to Masahiro Hara for not asserting his patent rights so this incredibly useful tool could be free.
If he didn't, one of the several other 2D barcodes would have caught on. I see non-QR ones around pretty often, though usually in industrial applications.
I remember back around 2009, there were a few of these in the newspaper: https://en.wikipedia.org/wiki/High_Capacity_Color_Barcode
I don't know how well it worked given the loose color registration. I didn't have anything that could read them at the time.
Are you sure they weren't just test colors? Most newspapers have them.
I cannot imagine what information they needed to encode that required that level of information density.
