In 2003, revenue from "online streaming music radio" was $49 million. By 2006, that figure rose to $500 million.

A February 21, 2007 survey of 3,000 Americans released by consultancy Bridge Ratings & Research found that as much as 19% of U.S. consumers 12 and older listen to Web-based radio stations.  In other words, there were some 57 million weekly listeners of Internet radio programs.

An April 2008 survey showed that, in the US, more than one in seven persons aged 25-54 years old listen to online radio each week.

In 2008, 13 percent of the American population listened to the radio online, compared with 11 percent in 2007.
