Internet radio’s drumbeat is getting louder.

More than half of Americans who go online listen to Internet radio services, and consumers who use them are using them more often, indicating the industry has become increasingly mainstream, according to a new study by Edison Research.

For the study, streaming services Pandora Media Inc., Spotify and TuneIn turned to Edison, based in Somerville, N.J., to survey more than 3,000 people age 12 and up about their online music consumption.

The study found that, for the first time, a majority of Web users — 53 percent, to be precise — listen to Internet radio outlets, including personalized streaming, live online audio and music on-demand.

“This study confirms what we’ve believed for some time: Audio streaming has arrived,” said John Donham, chief executive of TuneIn, a Palo Alto, Calif., company that aggregates online radio stations and streams to more than 40 million active listeners. “It’s not just that people are listening differently; more audio streaming means more overall listening.”

Slightly more than two-thirds of those surveyed said they listen to more online radio than they did a year ago as they access content on more Internet connected devices.

More than 80 percent of smartphone owners said they listen to some kind of Internet radio on their mobile gadgets.

“The advent of mobile listening and the proliferation of choices for the types of Internet audio have transformed the medium from niche activity to major media channel in under ten years,” Larry Rosin, Edison’s president, said in a statement Tuesday.

Almost 9 of 10 people listen to radio in their cars, but only 17 percent use Internet radio.

The growth of Web streaming doesn’t mean traditional AM and FM radio is losing out. The survey said 90 percent of participants listen to terrestrial stations.
