THEN AND NOW: What 12 candy bars looked like when they were first released

Since the mid-1800s, confectioners have been shelling out millions of candy bars a year to satisfy the sweet tooths of fans all around the world.

The majority of classic confections have gone through a few candy wrapper design changes over the years — here's how some of your favorite candy bars have evolved over the years. 

Hershey's chocolate bars had embossed labels.

Before beginning the manufacture of chocolate in 1900, Milton Hershey, creator of the Hershey's bar, was a successful caramel candy seller. Hershey began selling these bars for about a nickel each. 

The original wrapper was printed on glossy white paper and embossed with gold text. It featured the image of a cow and what appears to be a cherub, in a cacao bean, holding a chocolate bar.

Now, Hershey's chocolate bars have simpler packaging.

Now, Hershey’s sells over eight variations including Cookies ‘n’ Cream and Extra Creamy Chocolate and Caramel.

Snickers used to have white, orange and blue packaging.

Launched by Mars in 1930, the Snickers bar was named after the Mars family's favorite horse. 

And, in 1984, Snickers bars was announced as one of the "Official Snack Foods of the Olympic Games."
