What company makes gelato?

Excuse me, could you possibly shed some light on the question of which company is responsible for the production of gelato? I'm quite intrigued by this frozen dessert and have been curious about its origins. I understand that gelato is a popular Italian treat, but I'm not sure which specific company or companies are renowned for crafting it. Could you please provide me with some insight into this matter? Thank you for your time and assistance.
