2 and Z relationship
Some letters born to be lucky. Z(ed) is one of them. Come on… We’re talking about logos. Be more optimistic. Lucky side of “Z” is it’s sometimes seems to be the same as 2 (two - the numeric character).
Now, think about the meaning of “2″. Yes, we already know it’s a number comes after one. When you take it’s meaning as “the second” in a numeral string for two, you may name it as “Alternative” too. Yes, this is the point of this post.
In a marketplace, if there are generic and -stronger than you- brands, you may like to position your brand as alternative of them and wait your turn. This point of view was experienced and succeeded. Look at “We try harder” slogan of Avis.
ZDF is a German TV channel - Zweites Deutsches Fernsehen (Second German Television). Ok. They are 2nd channel and and their brand beginning with a Z letter already. But when you look at their logo, you can see their above mentioned competitive pretention easily. Did somebody put forward this idea into their logo creation process? We don’t know obviously. The only thing we know is, it’s a good work. Look at that:

Good idea and technically perfect design. Beautifull too.
