I'd never heard an origin story, either. The reason I'd heard of it, liked it, and buy it myself is because restaurants very conspicuously put it on their tables. If that wasn't coordinated marketing, then I guess it's luck. But was probably marketing. Even without a "sales team," someone had to be going to those restaurants and making deals with them.
