Which company introduced the first mass-produced chocolate bar?

the question needs to be changed, it's only true for the USA

bigden, Dove is pretty good.😋

bigden, “Terrible” is a little harsh. I manage to choke it down.

Yana, Hershey 's is Great chocolate 🍫 😋

It’s the first time I have heard that Hershey make “chocolate”. I believe the first chocolate bars were made by Cadbury in the U.K. They have been bought by Mondelez so are no longer making chocolate.

compared to European chocolate, American chocolate is terrible.

Putterill, What's the rest of the world 's answer ?
