It was founded in August 2008. , iHeartRadio was functioning as the national umbrella brand for iHeartMedia's radio network, the largest radio broadcaster in the United States with 128 million registered users as of 2019.

History iHeartRadio is owned by iHeartMedia, which was rebranded from Clear Channel in 2014. Prior to 2008, Clear Channel Communications' various audio products were decentralized. Individual stations streamed from their own sites (or, in many cases, did not owing to voluminous syndication and local advertising clearance issues), and the Format Lab website provided feeds of between 40 and 80 networks that were used primarily on Clear Channel's HD Radio subchannels, many of which transitioned to iHeartRadio unchanged. In August 2008, Clear Channel launched the iHeartMusic website, featuring entertainment news, national news, music content including albums, singles on demand, music videos, and access to over 750 Clear Channel radio stations online. On October 7, 2008, Clear Channel Radio launched the first version of iHeartRadio to the Apple iPhone and iPod Touch through the App Store. Twelve radio stations in 8 markets were included in this first release. In 2009, iHeartRadio was made available to BlackBerry devices and the Android operating system and then Sonos in 2010. September 2011 marked the official launch of the free, all-in-one iHeartRadio service featuring thousands of live radio stations and custom artist stations. The launch coincided with the inaugural iHeartRadio Music Festival, the annual two-day event hosted by Ryan Seacrest at the MGM Grand in Las Vegas. The app was expanded to the Xbox 360 and webOS. On April 20, 2012, iHeartRadio launched on the iPad. On June 8, 2012, iHeartRadio concluded a deal to power Yahoo! Music's Radio service, previously powered by CBS Radio.
