Iheartmedia, Inc.
One of the largest owners of radio stations in the United States, iHeartMedia also runs the iHeartRadio streaming app and a major podcast network, letting listeners tune in on air, online, or from their phones. Founded in San Antonio in 1972 as Clear Channel Communications — a name borrowed from "clear channel" AM stations that held exclusive use of their radio frequency — the company rebranded as iHeartMedia in 2014 to match the rise of its digital iHeartRadio platform.
