Drmyke3, I believe it was at the beginning of the SHM and it was Chas Fritz that did a brief calculation of the projected market size of potential bar codes and if they were able to capture just 5% of that market, in other words, register only 5% of the bar codes it would mean billions of dollars in revenue. He did the calculations on a flip chart, it wasn't a slide so you won't be able to find it. I think the cost of registering the bar code was based on a couple of hundred dollars annually, so a very reasonable cost for manufacturers. Maybe others remember the specifics of what was discussed.
