(answer to the question "What is your favorite brand?" by Interbrand)
Funny. All my top of mind brands are media (France Football, The Economist, BBC) Then I realize there isn't a brand I could put in such a list as yours. I respect many companies and naturally I do have favorites (ie models, authors, designers, cars...), but I'm more interested in the content than the shell, and I don't feel affection for a brand or a label. Even if it does happen (hard to avoid), I don't like the idea of having something writen (nor some logo) on me. I reckon it may have something to do with my being an author. As Roy Disney brilliantly reminded us, brand is for cattle. Being loyal to a brand is being as dumb as a cow. You are loyal to people or things you trust.
PS : be careful : picking faves could be dangerous when working for Interbrand !
(answer to the question "What is your least favorite brand?" by Interbrand)
That one I can answer a little bit more easily.
Since we're on LinkedIn, I'll start with a shared connection : Hummer.
My hall of shame : Microsoft, Halliburton, Bud, Wal-Mart, Fox News, Rush Limbaugh, Billy Graham, The Sun (a UK toilet paper brand passing for a newspaper brand), World Wrestling Entertainment, The New York Yankees, The Carlyle Group and the Discovery Institute.
At the risk of infuriating a few contacts, I'll put a slice of Dunkin' Donuts, Taco Bell, A&W Root Beer, Jif et al on top of it (barf bag, anyone ?)
