These days every company has a logo. It is the first identifier of the company to the public they will be dealing with and as such (at the risk of repeating myself) it has to reflect the personality and core values. I came accross this video recently and for me this says everything a client should know about having a logo in just a few minutes.
Designers are frequently commissioned to design a company logo, we take our work very seriously, we pour hours of our time working and reworking the ideas with the client and ensuring that the final mark will live accross all of the many platforms we have to deal with in todays world – from the tiny 16 pixel icon on twitter to the giant 12 metre hoardings – they all need to be legible.
Anyway, enough from me, enjoy the link
