ATLANTA, GA – (April 10, 2008) – Internap Network Services Corporation (NASDAQ: INAP), a global provider of end-to-end Internet business solutions, announced today that LKCM Radio Group, the parent company of multiple Texas-based country music stations, has selected Internap’s ad delivery service and content delivery network (CDN) to reach a larger audience and increase revenue from its online presence through sponsorship and advertising.

LKCM Radio Group owns nine Texas and Oklahoma-based radio stations, including country station 95.9 The Ranch and classic country station 92.1, and has been streaming radio online for approximately five years. It recently adopted robust Internet business solutions from Internap, including ad delivery technology and a custom media player, to increase its listenership and effectively monetize its Web presence.

“We selected Internap as our online services provider to help us stay ahead of the competition,” said Andy Meadows, operations director at LKCM Radio Group. “Our Web presence plays a huge role in our success, and Internap has helped us transform our sites into an effective extension of our popular broadcast programming, which our audiences continue to enjoy. Through working with Internap, we are able to target markets we couldn’t reach before, boosting our business and expanding our audience.”

Internap’s CDN, backed by its 100 percent Service Level Agreement (SLA) guarantee, enables LKCM Radio Group to reliably stream its programming online, reaching listeners that were previously outside of the company’s designated market area (DMA). Internap’s professional services team made it possible for LKCM to effectively extend its brand by developing personalized audio players to fit the stations brand image.

Internap has considerable expertise and powerful network solutions for the broadcasting market. These solutions help radio stations generate revenue from their online broadcasting in order to subsidize the cost associated with having a Web presence. The company’s technology offers real-time tracking and user-targeting, promising advertisers maximum ROI by providing comprehensive reporting data, including audience metrics.
