Whole grain popcorn???

O.K. so I was making myself some popcorn this evening when I decided to read the box. Normally, I buy Act brand popcorn, but apparently Walmart decided not to carry it anymore (or maybe they were just out). I bought two boxes of Orville Redenbacher. One with lots of yummy butter, because my son wanted it, and one that said 97% fat free (should've known better). Anyway, I was reading the box and noticed that it said 100% whole grain popcorn. hmmmm. Can anyone tell me what other kind of popcorn there is? Isn't the kernel the "whole grain?" Is there an "enriched" version? Think maybe its a marketing ploy??? I love reading labels anyway. Once I bought this drink mix called "Fruit-teas" that was supposed to taste like a fruity tea. On the back it said, "This product contains no fruit and no tea." The funny thing is, we fall for these marketing lies most of the time and don't even know it.
