By 1977, Pittsburgh Brewing Company was one of just 40 breweries left in the country. To rebound from difficult years, the brewery introduced a new light beer, Iron City Lightâor IC Light. IC Light's aggressive marketing campaign targeted the young beer drinker.
Corona Light was introduced in the United States in 1989 and became the first imported beer to sell more than one million cases in its first full year of distribution. It has steadily grown since its inception and is now the #1 Imported Light beer in the U.S. Corona Light is the #6 imported beer in the U.S., and the #1 imported light beer.
