Schlitz

A little history of Schlitz from wikipedia:

The Joseph Schlitz Brewing Company was an American brewery based in Milwaukee, Wisconsin and was once the largest producer of beer in the world. Its namesake beer, Schlitz, was known as "The beer that made Milwaukee famous" and was famously advertised with the slogan "When you're out of Schlitz, you're out of beer". Schlitz first became the world's top beer producer in 1902 and enjoyed that status at several points during the first half of the twentieth century, exchanging the claim with Anheuser-Busch multiple times during the 1950s.
The company was founded by August Krug in 1849 but acquired by Joseph Schlitz in 1858. Schlitz would eventually be bought by Stroh Brewery Company in 1982, and subsequently be sold again along with the rest of Stroh's assets to the Pabst Brewing Company in 1999.

The company flourished through much of the 1900s, starting in 1902 when the production of one million barrels of beer surpassed Pabst's claim as the largest brewery in the world. Schlitz was continuously in competition as one of the top breweries in America for the next 70 years. While prohibition forced the suspension of alcoholic brewing, the company changed its name from Brewing Company to Beverage Company and adapted its slogan to "The drink that made Milwaukee Famous."
Popularity of Schlitz's namesake beer, along with the introduction of value priced Old Milwaukee in 1955, kept the brewery on a strong financial footing. However, changes implemented in the early 1970s led to its eventual fall.
Faced with the need to meet large volume demands while also cutting the cost of production, the brewing process on Schlitz's flagship Schlitz beer was changed in the early 1970s. The primary change involved using high-temperature fermentation instead of the traditional method. Schlitz also experimented with a continuous fermentation process. even designing and building a new Baldwinsville, New York, brewery around the process. The reformulated product resulted in a beer that not only lost much of the bite and taste of the old formula but spoiled more quickly, rapidly losing public appeal.
Schlitz remained the No. 2 brewery in America as late as 1976, but ongoing problems with formula changes continued the downfall. The ultimate blow to the company was a crippling strike at the Milwaukee plant in 1981, which led to serious financial difficulties and acquisition by Stroh Brewery Company of Detroit, Michigan, after a lengthy 1982 legal battle.
What remained of the historic Schlitz Brewery complex in Milwaukee was transformed with Tax Increment Financing and other government support into a mixed-use development called Schlitz Park.

During the reformulating period of the late 1960s and early 1970s, the original Schlitz formula was lost and never included in any of the subsequent sales of the company. Through research of documents and interviews with former Schlitz brewmasters and taste-testers, the 1960s formula was reconstructed; the new beer, along with a new television advertising campaign, was officially introduced in 2008.

Schlitz was my beer of choice throughout college, because at $6 a case, I couldn't beat the value.  It was also cool in that time frame when they brought out old style cans in honor of the fiftieth anniversary of WWII, when Schlitz was provided to soldiers, and was also the #1 selling beer in America.  I didn't realize that Schlitz introduced Old Milwaukee.  I thought it was always a Stroh's beer.  I guess it doesn't make sense that a Detroit brewery would start another beer named Old Milwaukee.  Here is a link to a detailed history of Schlitz from 1933-1969.
