With most people listening to talk radio on the go, iHeartRadio — the digital arm of radio giant Clear Channel — figured its mobile apps should make finding the talk easier. Updates to the apps Monday add a directory for talk content so users can browse and select from drop-down categories; a side navigation pull-out screen; and the ability to customize and access Live and Custom Station preset favorites. The update also adds new segments from “The View” and “Jimmy Kimmel Live” coinciding with with the fall television season. The updates get talk content more quickly to listeners’ ears where people are looking for digital radio most — on their phones. Unsurprisingly, with most online radio listening is moving to mobile devices, 60 percent of people listening to iHeartRadio Talk since its beta launch in late July are doing so with a portable device, the company said.
