This post might lack a clear connection to packaging but it is such an interesting piece of work made by Philip H. Howard at Michigan State University. He has recorded and plotted the flora and fauna of soft drinks available in the Michigan area.
I can’t say that I agree with his point, which is that the variety and choice of soft drinks for the consumer is more imagined than for real when you look at the owner structure. But I like the way he has meticulously recorded and then visually displayed the universe of soft drinks. One of the best overviews I have seen. http://bit.ly/d9BY23
