Light beer
Light beer is beer with lower calorie or alcohol content than other types of beer. In the United States, "light beer" is beer with reduced calorie content. Prior to the 1970s, "light beer" had other meanings in the United States. In Australia, Canada, and the United Kingdom "light beer" is beer with lower alcohol content than regular beer.
Reduced calorie light beer began to be mass marketed in the United States in the 1960s, but the first successful brand, Miller Lite, was not marketed nationally in the United States until 1975.
