Each 12-panel bar will feature 12 different emojis. The company is using a total of 25 different popular emojis in all, including the iconic smiley face, sunglasses face, winking face, thumbs-up, clap hands, and other familiar figures. Both regular and snack size bars will include the emojis.

In what amounts of a relatively limited run, Hershey's will make 25 million of the emoji-imprinted bars. That's an estimated one-tenth of one year's production. The packaging will feature a large emoji as well.

Milton S. Hershey started with a Philadelphia candy shop in 1873 and first made the now-familiar milk chocolate Hershey's bars in 1900. The company has added other products through the years, including chocolate syrup and the well-known individual cone-shaped Kisses, and has included other ingredients inside the iconic large- and small-shaped rectangular bars that first made it famous, including Cookies & Creme and Reese's Pieces. The top imprint of the bar has long been the word Hershey's.

The company also makes other well-known products, including Kit Kat, Mr. Goodbar, and Reese's Peanut Butter Cups.
