Oh, and the light beer thing... When light beer first showed up here in the USA, it was an instant success and the people, apparently, wanted it more than any other type of beer. It was also harder to make, so the bigger national breweries were able to capitalize on that, and many smaller breweries went out of business. Many more were purchased by the larger ones (IE Budweiser) and either absorbed or dismantled. That was in the 50's, I believe.
