TOKYO – 30 June 2008 – Limelight Networks, Inc (NASDAQ: LLNW), today announced today that the company will provide enhanced content delivery services to GREE, the second largest social networking service providers in Japan. GREE’s content is distributed for over 5 million unique users.

“We believe that Limelight Network’s customizable content delivery network and enhanced technology meets GREE’s demands for services with short term deployment that provide users with providing fast, stable content delivery,” said GREE in a statement.

Because Limelight Networks’ CDN uses servers consolidated in datacenters, it boasts a large capacity that enables it to store a large number of files for distribution. This capability makes it ideal for long tail businesses such as GREE’s SNS which are designed to offer users as large a variety of content as possible with short response times by enabling high cache efficiency even for rarely downloaded files. Moreover, because the company’s CDN is designed to handle high capacity, popular content, it is able to maintain fast response times even when access is widespread from PCs and mobile devices.
