Actually, only Apple's logo here does not need any title text because it reads exactly like it looks.
Starbucks just joined the exclusive club of de-clutered brands Apple and Nike. Yay for formerly-known-as-Starbucks company.http://www.starbucks.com/preview
The first thing I thought when I found out Apple had done it was 'At last, I don't have to drone on about Shell anymore'. I like the proposition and it is worth debating and in some cases it works, but for me personally, the concept of a brand taking the decision to de-clutter just for the sake of it or as a (possibly arrogant) show of brand awareness by the masses or even just for keeping-up-with-the-jonses is foolhardy at best. I feel, if you take the motor industry examples, for their identity to not include the marque and the typeface therein would weaken their identity. That aside this shows one thing: the logo is dead, long live the logo.
