National Brands

When I was online the other day, I came across an article titled, "Americans Continue to be Loyal to National Brands".

This article was very interesting. It stated that almost half of Americans are indeed loyal to National Brands. National brands can include everything from food, drugs, beauty care, etc... Brands such as Kraft, Old Spice, Gillette, and so on. It also says that National Brand Buyers are more likely to recommend the brands they use, movies they have seen, cars, television shows, etc.
At first I couldn't believe that half of the country bought National items. Then after thinking about the article it was more believable. I know personally when I go to the grocery store I always buy the same brand of ice cream, deodorant, shaving cream and razors, etc. This is just because I am more comfortable when using these products vs. other products.  I don't even think about trying a new product, I just grab what I need and the brand I use. After looking at what my roommates purchased at the store, one of them was the same as me, with the same razors, deodorant, etc. while the other two just bought whatever was on sale that week.
After reviewing this article, I think many people just get so familiar with the products they use it is almost second nature to continue buying the same products.
Are you a National Brand Buyer, or Local Brand Buyer? Why?
