Mountain Dew was invented in Knoxville, Tennessee in the 1940s and first marketed in Tennessee and North Carolina in the 1940s and across the US in 1964. It has a bright yellow-green color that is translucent when removed from its characteristic green bottle. Mountain Dew comes in various product variations like different flavors and special edition bottles. A 20 oz can typically costs between $2-$3 while a standard can costs around $1-$2. It is widely available wherever soda is sold. Competing sodas include Mellow Yellow, which has similar ingredients but a slightly different flavor.
