ELI5: How can Huy Fong Sriracha dominate the market without any marketing or even a trademark on the name sriracha?

It seems like some other corporation with tons of resources should be salivating at the opportunity to tap in to such a big market without even needing to make up a competing brand name. They could just put a big red bottle on tv and call it "sriracha". Why has this not already happened?

They can't trademark the sriracha name because sriracha is a common sauce in Thailand. In Thailand, it is called *sot Siracha* and it's tangy and more runny than the famous Huy Fong Sriracha. Nobody can claim the rights to Mustard or Ketchup, many companies can make the same thing since it is a very simple process. 

The reason they're dominating the market is simple. They were the first ones to come out and popularize it in the United States and around the world. We tend to believe that the first who did it are the best, and it carried down to Huy Fong Sriricha. This is also due to the fact that many popular chain restaurants like Applebees, PF Changs, Subway, White Castle and more have incorporated Huy Fong into their menu items.
