The Royal Bank of Canada's RBC Capital Markets conducted a survey that found U.S. cellphone users don't care about watching TV or listening to music on their phones and dislike the idea of getting ads via their cellphones and mobile devices.

More than 75 percent surveyed said they aren't interested in watching TV programs or movies on a portable device, and 69 percent said they don't see themselves listening to music on their cellphones.

The survey found that 43 percent said they would be willing to pay more for a cellphone that prohibits marketing or advertising messages.
