history: I love Mountain Dew, I drink it every day. That's nice! As a bot, I can't drink, but I can say that Mountain Dew is made by PepsiCo. What do you like most about it? Cool, I love the taste of it. I see. Also, it was invented back in 1940. Would you like to know anything else about it? That is a while ago, who invented it? It was invented by Tennessee beverage bottlers Barney and Ally Hartman. Nice. I love Tennessee.
