Committed to be the first to deploy Visual Radio.

Today (May 12) Infinity Broadcasting launched the nation’s first multicast HD radio channel by a commercial broadcaster on WUSN-FM (US99), the group’s top-rated country station in Chicago.

The multicast channel is the latest initiative from Infinity to bring radio into the digital age. Last month, the Viacom-owned radio group announced the nation’s first radio format based on content from podcasts.

Infinity has also committed to be the first U.S. broadcaster to deploy Visual Radio, a new service from HP and Nokia that will allow listeners to tune-in to local FM radio stations via mobile phones while simultaneously receiving interactive information and graphics synchronized with the radio broadcast.
