We all have a favorite childhood treat that got axed by corporate overlords. Personally, it's Altoid Sours — but for many marshmallow fans, it's Hershey's S'mores bars. According to commenters on social media, the bars are well missed. According to The Hershey Story, a museum dedicated to the history of the company, the gooey chocolate bars were released in 2003 and discontinued in 2012. While the company never disclosed their reasons, it's likely that the bars were a victim of flagging sales.
