The "Is it time to retire the black and white logo?" post continues to receive much traffic and many comments. You should read them all.
Robert has just argued in favour of keeping the black and white logo and in doing so has included the best and the worst points of the debate.
Best point: "TELEVISION - Yes, TV logos are mostly in color. However, they are requested by the station in black and white. The TV studio then generates the color from the submitted bw art and Pantone® match chips."
That's a valid point and I bet there are many forms of media we don't know about yet that will operate in the same way.
Worst point: FAXING - Necessary for rapid faxing of info. The company does have its logo on the fax sheet doesn't it.
