804.872 - 830.808 Josh

So like you said, until around 1800, it was mostly for the upper class. But then, like everything else in industry in America around that time, manufacturing became more widespread and cheaper, and all of a sudden you had... warehouses that were big freezers, and you had shipping. You could ship things cold and frozen. Right, so you had the manufacturing aspect in place.

831.108 - 835.869 Josh

Yeah, homogenizer machines, electric power, mechanical refrigeration, basically.

835.929 - 859.499 Chuck

But even still, you had... You had the manufacturing in place. The distribution, though, was still limited to, say, like a store, somebody who could make money by investing in some freezer cases and then selling it to the public. It wasn't until ice boxes became widespread in America that the ice cream industry really blew up because then you could sell to the guy down at Pops.

859.72 - 866.082 Chuck

You could also sell to Pops' next-door neighbor who took it home to keep in his freezer.

866.202 - 867.363 Josh

And thank God that happened.

867.719 - 882.298 Chuck

Yeah, and actually, as far as making ice cream, the hand crank ice cream maker that used rock salt and all that stuff, that was invented by a woman named Nancy Johnson in the 1830s.

883.939 - 909.106 Chuck

1850s i think yeah and she patented it and apparently everybody ripped her off she sold the patent for like 200 bucks and the guy who bought it from her turned around and likes made a fortune off of it but i guess he ultimately got ripped off by a bunch of copycats but that that same thing is still in use today like you can go buy the johnson crank that same yeah the johnson crank ice cream maker and make your own ice cream the 1850s way

911.16 - 926.687 Josh

Well, you mentioned take-home ice cream being a big deal as far as it's spreading. I do have a little modern stat released from a few years ago. That is still the biggest part of the market. 67% of the overall market is take-home ice cream.
