Harris surveyed mobile users ages 13 to 19, and found that more than one-half of respondents were not interested in mobile ads, even in exchange for some type of incentive. Incentives are likely to be part of many mobile ad campaigns, because a majority of users are opposed to mobile marketing in general.

For the past three years, Synovate has surveyed mobile phone users in the US on behalf of the Mobile Marketing Association. Each year, at least three-quarters of respondents said they were not interested in mobile marketing.
