A grape tomato is a class of tomatoes believed to be of southeast Asian origin, shaped similarly to the oval plum tomatoes but having the small size and sweetness of cherry tomatoes. Grape tomatoes produce small and typically oblong fruits. Introduced to the worldwide market in the 1990s, they have gained substantial popularity, due at least in part to their higher sugar content compared to regular tomatoes, and due to their smaller, bite-sized shape. – Wikipedia
