Brands, Strategic Function, & Social Media

In your initial post, comment on all 3 topics listed below.
Favorite Brands
Tell us about two or three brands you admire, and why you admire them. Is there a "brand idea" you see behind them (refer to the module on brand ideas for guidance)? What makes those ideas give lift and power to the brand?
