Are you saying the Wikipedia English article on Cherry Tomatoes is inaccurate? According to them, Cherry tomatoes go back to 16th Century in Europe and earlier in the Americas... Same article states that the Israeli research applies to the Tomaccio versions of cherry tomatoes. Anyway, do you know how popular they are in Israel compared to other tomatoes today? Great course on Hebrew!
BTW, grape tomatoes are not the same as cherry tomatoes. In Seattle area (where people are known for eating out!), there is a reputable restaurant supplier where we shop sometimes and they do NOT carry cherry tomatoes but they do sell the grape tomatoes. The two varieties, while similar to the casual consumer, have quite different histories/origins...
I could not reply directly to your message... If you go to national chains like Costco and Sam's Club, you will find them but they are only a portion of the tomato sections. As far as regular stores, I talk for So Cal and Seattle area stores. If you check sites as USDA.gov and chartsbin.com you should see some "official" stats in that regards. BTW, we love cherry tomatoes.
Also, what do you mean by "pretty fair sized selection?" Are you saying that in Central Texas you can find more than one variety of cherry tomatoes in the same store?
My original question was related to Israel, though... Hth, Daniel.
