Brands & Labels & Logos, Oh my!

When thinking about brands and labels, the first companies I think of are Pepsi, Verizon, Apple, McDonalds and Listerine.  Each has a very recognizable logo/label, at least to me.
Verizon with its red checkmark, Apple with its apple and bitemark, McDonalds golden arches and Pepsi's red, white and blue circle.
Though Listerine doesn't really have a specific picture for a logo, but it's as easily recognizable. Whenever there's an advertisement for mouthwash, no matter how ridiculous, it is probably for Listerine. Like this one, for example. Strange, but identifiable as the Listerine brand.

The photo below is an example of the Pepsi logo, taken Spring 2013.

Despite slight alterations to its logo over the past forty years, people can very easily recognize the Pepsi brand.  Whether they drink a lot of soda, or none at all.
