Millions of Americans love their chocolate bars and can't imagine a life without their favorite sweet treat.

Time magazine recently polled candy experts and historians to come up with a list of which products have had the biggest impact on the candy business.  

The experts came up with 13 candy bars.

Here's a look at the top 4: The Kit Kat finished on top, according to the Time survey. Historians say it was the first candy bar to promote sharing and the first to gain a truly global following.

To show you how far the Kit Kat has come in its world domination, an all-Kit Kat store opened in Tokyo in January featuring flavors like edamame soy bean, purple sweet potato and wasabi. 

The classic Hershey's Mile Chocolate bar was just behind the Kit Kat. Since its first bar debuted in 1900, Hershey’s has become one of the world’s most recognizable brands. World War II soldiers munched on the iconic candy bar and there's a $23.5 million museum dedicated to its legacy. 

The world-famous, triangular-shaped Tolberone is number three, and Nestle's Milk Chocolate rounds out the top 4.
