Was Jamba Juice an innovator of its kind? What and who was before them? I need to know if it was the first widespread smoothie store to take over the juice industry what else existed in the 90s what kind of smoothies did people drink.

I could just look this up but I don’t want to ruin my curiosity with immediately knowing which is dumb and counterproductive. But seriously like for example blockbuster- there wasn’t much before it right? But there were probably mom and pop video stores or something of that nature I’m not sure I’m determined to find out at some point.
