When MD changed their label last year itw as transparent, but now im seeing more and more of the label (2liter) not transparent, I kinda liked the transparent look.
I think diet still is all transparent
and no there wasnt a contest or anything on the bottle.

they did the same thing with sierra mist too a few years ago. Pepsi One was shiny and aluminum looking last year when they changed the logo and taste but is just a regular label again.

Maybe the non transparent labels did better in a focus group or the old lables may have less problems in the manufacturing/unit application process?

The same happened with Pepsi's 7UP here... When they released in the beginning the new label, it was transparent, but when Pepsi changed the bottle of their products here, the size of the label changed and stopped being transparent.

Dew 20oz labels are transparent here in SoCal. I want to say 2 liters are also. Diet Dew is not.

i like the newer non-transparent labels because before the regular and diet looked too similar
