It's an age-old question: If a marketer puts a QR code in an in-flight magazine -- on a flight without Wi-Fi -- what was said marketer smoking? The answer -- as it recently occurred to Allison Owen, Digital Media Specialist at The Integer Group -- is obvious. (Crack, we assume.) It is, however, a perfect example of the many ill-conceived mobile marketing campaigns out there, today. Likewise, Brian Stoller, Leader of Digital Strategy at Mindshare North America, hates seeing QR codes in subways in New York City. Even if he didn't want to engage with the campaigns, which Stoller admits he rarely does, there's no way to do so. (Not yet anyway, as New York City is working on Wi-Fi-supported subways.) Worse still, Stoller adds, is when QR codes drive traffic to non-mobile optimized sites. What sort of brand would do something so stupid?! Coke, according to Stoller.
