The 4 Ws Of Messaging.
The 4Ws of messaging are what you say, where you say it, when you say it and to whom you say it. I invented them in reaction to seeing this poster the other day.
For non-UK readers, the Northern Line is one of the lines of the London tube/subway system and one that has recently been synonymous with torrid travel. So, what is being said is clear enough. Not award-winning, but clear.
Unfortunately, I did not see this poster in London. Rather, it was on the back of a bus stop in a side-street in a commuter town. So, not the optimal where - especially as the side-street was nowhere near the town's station. And that means that commuters who might have a knowledge of the Northern Line were unlikely to see it.
So, not the optimal who either.
None of this is necessarily the fault of the non award-winning copywriter and art director (unless the brief was to create a nationally relevant campaign) even if it does suffer from metropolitan centricism. But it does serve as a reminder that media buyers should focus on the message they're placing as well as the audience in front of whom they're being asked to place it.
