Oh, Schlitz: How a Historic Ad Campaign Helped Kill America's Biggest Beer Brand (vinepair.com)

I can still taste this beer. Unforgettably bad.

This headline implies that advertising was primarily to blame for killing Schlitz when the post itself admits that the beer itself had radically changed formulas in favor of a cheaper brew and had lost favor before the ads in question ran.

Corn syrup and silica gel? Just what every beer drinker in their brew. Idiots!

Have had much shitz, I remember, from schlitz, but I must drink and not surrender.

As it's always, never change a running system. If you want to build them both side by side.
