TEMPE, Arizona, June 18 /PRNewswire/ --

- Limelight Networks Enables Major European Online Advertising Campaign
Management Company to Deliver Targeted Campaigns Reliably

Limelight Networks, Inc. (Nasdaq: LLNW) today announced that Smart
AdServer will use the LimelightDELIVER object delivery service to increase
the quality of service SmartAdServer provides to international clients,
manage peaks of online demand, and decrease the cost of bandwidth.

Smart AdServer is a large European provider of adserving and digital
marketing services to media agencies, ad networks and publishers. Since its
founding in 2001, the company has quickly become a key player in France and
is growing its business rapidly throughout Europe because of the unique and
innovative functions of its solutions. Today the company has over 110 clients
and 1000 Web sites on four continents.

As a company managing the delivery of rich online media content, Smart
AdServer was challenged with dealing with a multitude of local and
international clients with differing content sizes, and locations. Through
LimelightDELIVER, Smart AdServer is now able to control how it publishes and
presents content to customers, assuring that it is delivered to the correct
audience reliably and in the best fidelity possible, whenever and wherever
advertising content needs to be streamed.

In the competitive world of creative advertising, where every passing
second can mean the difference between an effective or failed ad, successful
content delivery is crucial. In order to ensure that customers locally and
internationally receive content at a fast, reliable speed, Smart AdServer
began progressively moving customers over to Limelight Networks on April 21.
With Limelight Networks, Smart AdServer customers will receive faster
response times and improved quality of delivery.

"Smart AdServer's international activity is growing fast, this is why it
was important for us to work with one of the leading providers in enabling
content delivery across the internet. We're pleased to be using
LimelightDELIVER to help our customers better manage their online campaigns,"
said Cyrille Geffray, Managing Director at Smart AdServer. "Equipping our
customers with better management tools means we're able to help our customers
gain a clear competitive advantage."

Limelight DELIVER offers advanced management tools to help with
publishing and presenting content. With its Geo-Compliance option, users can
ensure that content is not accessible outside of a defined geographic area,
ideal for managing media licenses with geographic restrictions. In addition,
with FLV Seek capabilities, downloads can start from any point users choose,
so they enjoy faster access to the content they want.

"We are pleased to be working with Smart AdServer to enhance the
performance of their international adserving and digital media business,"
says Chris Townsley, director of strategic sales, Limelight Networks, United
Kingdom. "The targeting and geo-compliance features of our LimelightDELIVER
product are perfectly suited to enable a growing business like Smart AdServer
to provide targeted, international services to their customers."
