How did frozen orange juice concentrate revolutionize history? (Please if you give me an answer or a link, do not have it be based on Orange juice I need FROZEN ORANGE JUICE CONCENTRATE)

Thanks!

I remember when frozen orange juice concentrate first came in the market in the late 1940s. Before then, it was a pain to squeeze oranges for our morning oj. However when we could just add water to the frozen concentrate, we could have oj easily at a reasonable price.
