A new report from Forrester Research puts a damper on the excitement around the prospects for mobile advertising, at least in the States: a whopping 79% of the US consumers surveyed said they find the idea of ads on their mobile devices annoying. Most expressed little or no interest in receiving ads, even when those ads are part of a free content/app offer; a mere 3% of consumers said they trust mobile ads; and only 1% said they might be influenced by text ads on their phones.
