VeriSign Helps Clear Channel Radio Stations Lock on to Listeners With Mobile Services

MOUNTAIN VIEW, CA (Marketwire) -VeriSign, Inc. (NASDAQ: VRSN), the leading provider of digital infrastructure for the networked world, today announced that Clear Channel Radio has selected VeriSign Interactive Applications Services to deploy a robust suite of mobile services that strengthen the connection between listeners and their favorite radio station.

Clear Channel Radio launched the interactive mobile services in New York in May 2007, and expects to bring close to 100 additional stations across the U.S. on-board by the end of 2008.

The VeriSign-enabled services benefit both the listener and the individual radio stations alike. Listeners can now send text messages directly from their mobile devices to the studio, participate in contests, receive an alert before their favorite song plays, make requests and dedications, and view the last 10 songs played on their favorite stations.

"We selected VeriSign for this nationwide program because VeriSign is capable of integrating the technologies and applications we need into simple to use, comprehensive services," said Jeff Littlejohn, Executive Vice President Distribution Development, Clear Channel Radio.

The integrated VeriSign services adopted by Clear Channel Radio for listeners with appropriate carrier data plans and compatible mobile devices include:

                --  SMS services that allow listeners to exchange text messages directly
                with radio stations.
                --  A customized WAP mobile portal that presents each station's look and
                feel, and allows listeners to view and purchase available content and
                services.
                --  A J2ME portal that is installed on the consumer's mobile device,
                allowing listeners to access station-specific services, and even purchase
                content and services.
                
"Consumers increasingly prefer mobile devices for accessing content and services, a trend that is prompting the world's largest brands to make mobile communications an integral part of their marketing campaigns," said Oliver Holle, Vice President of Mobile Applications, VeriSign. "We are excited to work with Clear Channel Radio to help them strategically leverage America's passion for mobile applications messaging to extend its brand beyond the radio dial and open new avenues for building incremental revenue and listener loyalty."
