Orion Confectionery started to sell a similar product known as "Orion Choco Pie" in 1974. In 1973, a member of the Tongyang&＃39;s R&D team had visited a hotel in Georgia, US, and was inspired after seeing chocolate-covered sweets in the hotel&＃39;s cafe. He returned to South Korea and began experimenting with a chocolate biscuit cake. After experimentation with marshmallows and biscuits, the Choco Pie was created.The name "Choco Pie" became famous when "Orion Choco Pie" was first introduced by Tongyang, and the cake became well-received by many Korean children and senior citizens because of its inexpensive price and the white marshmallow filling. Tongyang Confectionery later renamed the company to Orion Confectionery due to the success of the "Orion Choco Pie" brand.
