Why Would I Have What He's Having?
So, I've been noticing a plethora of ads (such as the one above) that feature "real" people. They're cheaper than discredited celebrity endorsements.
The trouble is people don't believe they're average and they certainly don't want to identify with the typical customer. They don't see one of us, they see someone they'd cross the street to avoid.
Far better to focus on your customers' aspirations than some aggregated categorisation that exists in the marketing department and probably nowhere else.
