The Direct Marketing Association, a lovely group dedicated to forcing ads down your throat, have done a study that found that while a mere 7% of cellphone users are open to receiving ads on their phone, a much more significant 24% say they've responded to such ads on their phone. A whole quarter of the phone population responding to ads? That has advertisers salivating, so you know that phone ads will be the norm soon enough. So, lets say they came up with a deal that paid for half of your bill if you agreed to watch a few ads a day on your phone. Would you do it?
