By the 1970's fewer than 40 breweries remained. Most of these beers were very uniform and bland. The United States had by this time developed a reputation for having the world's worst beer. There were reasons behind this. After WWII, in order to appeal to women, milder tasting beers were developed. Thus, the origin of "light" beer.
