I was sitting in McDonald's on Pentonville Road yesterday, minding my own business, when a whopping great banner flew past the window, towed by a helicopter. Reaching for my specs, I was able to make out the logo: SATNAQ. This not being a product I'd heard of (comes with living in the back of beyond, I assumed), I began to speculate on what it actually was. Not surprisingly, my first guess was something to do with satnav - I mean it almost says 'satnav', although surely they wouldn't let a giant typo flap aimlessly around London's grey skies? Ok... with the credit crunch being most commentators' diet of choice right now, my thoughts moved on to finance... the 'NAQ' bit sounding as if it's got some vague connection with those weird US markets. Perhaps it's even a combination of the two? A service that navigates the investor through the turbulent storms threatening to flatten one's strawlike home and leave the piggy bank shivering at the mercy of Mr Wolf. Naw... not that either. So what is SATNAQ? ................................................................................................................................. You probably spotted that I'm being bit a little bit ingenuous here: but the fact is, while the one half of London that bothers to raise its eyes skywards sees an ad for QANTAS, the other half gets regaled with SATNAQ. Quite why the budget didn't stretch to a double-sided, non-see-thru banner I can't imagine. Surely it would be cheaper than having the helicopter fly backwards as well as forwards (if you see what I mean), and certainly kinder on the environment. In the meantime, I'm wondering if some enterprising cockney hasn't come up with a product called SATNAQ, in order to take advantage of the free advertising currently on offer. It would be an interesting test to demonstrate whether advertising really works.
