Another Brand Name Company Turns to RadioCentral to Strengthen

Online Services, Extending Usage and Encouraging Repeat Visitors

RadioCentral, Inc., a network radio company that provides custom interactive radio programming for commerce and content Web sites, and About.com, the Internet's most complete targeted environment for users and marketers, today announce the launch of the About Radio Network at www.about.com. RadioCentral is combining its industry-leading radio programming and advanced streaming audio with About's site interface and design to offer free to users some of the best music and sound fidelity available on the Internet.

This new radio service has the potential to reach the more than 26 million users that visit the About Network. According to a recent Jupiter Media Metrix report, About is the No. 1 news and information site and 7th largest Web property on the Internet. In addition, Jupiter Media Metrix also reports that About is one of 14 top online properties that control 60 percent of aggregate minutes spent online in the United States.

"Internet radio offers a powerful branding tool that enhances the user's experience and extends the amount of time spent on site," said Mark Josephson, General Manager of About.com. "RadioCentral combines audio quality with a deep understanding of programming gained from years of radio industry experience. These qualities made RadioCentral the clear choice to develop the About Radio Network."

"About.com is one of the biggest Internet success stories, known for innovation and building business models that make money," said Eric Rhoads, president and CEO of RadioCentral. "Having About join our network of premium radio stations will help put RadioCentral over the top as a leader in online radio listening."

Internet radio is gaining momentum as a recognized tool by which companies can monetize their online properties, as well as extend the company brand image by offering their Web site visitors a compelling visual and aural experience. RadioCentral's customized audio player is visually branded to blend into the company's existing Web site design and personality. Further, top DJs are able to drive home brand messages through on-air voice delivery. In addition, RadioCentral creates radio content that is FM radio-quality, but with true CD-quality sound and less commercials than local radio stations.

Leveraging their radio expertise, RadioCentral has created three separate radio formats or "radio stations" for the About Radio Network: About Rockin' Hits, About Pop Alternative and About Slow Jams. RadioCentral has worked closely with About to create customized radio programming that is consistent with About.com's target audience and typical users, including music content, DJ voice-over and station identification references.

The Power of RadioCentral

-- High Fidelity -- Using its exclusive "High Definition Audio" technology,
RadioCentral provides the highest quality sound fidelity available that is
exceptional regardless of whether the listener's Internet access is high-speed
or dial-up.

-- "Live Radio" Sound -- A proprietary-technology enabling continuous mixed
streams of voice and audio blended together at all times. This "radio style"
method of audio delivery is familiar and comfortable to listeners, but hard to
achieve for most online radio providers. It reduces listener fatigue and
encourages longer listening and repeat visitors.

-- Interactivity -- RadioCentral leverages the proven efficacy of terrestrial
radio and couples it with the interactivity of the Internet. Consumers are now
able to act immediately after hearing audio prompts for products and services.
In addition, RadioCentral's network of affiliate Web sites gives advertisers
increased ability to reach targeted audiences.
