Mobiltel Bulgaria is Fifteenth Operator to Choose RealNetworks to Power Music Service

Mobiltel subscribers gain 'All You Can Eat' functionality

SALZBURG, Austria and SEATTLE, March 15 - RealNetworks(R), Inc. (RNWK), the digital entertainment services company,
transitioned Mobiltel Bulgaria's music service to the Real platform on
March 10, 2010, adding all-you-can-eat functionality and continuing its
strong momentum across Europe. This is the third deployment under Real's
4-year agreement with mobilkom austria group (MAG), providing Mobiltel's 5.4
million subscribers with access to the most feature-forward mobile music
service in Europe.

"RealNetworks is a global leader in mobile music and with its strong
presence in Eastern Europe, is a perfect fit for MAG and Mobiltel," said
Evgeni Karakanovsky, marketing data director for Mobiltel Bulgaria. "We
believe that our subscribers will be more likely to utilize mobile music-as
we've seen happen with our sister company A1 in Austria-due to the increased
simplicity and elegance of the interface and dual download capability."

Mobitel's migration to RealNetworks' music platform provides subscribers
with flexibility and choice for downloading music to their mobile devices. By
subscribing to the Music Unlimited package for just 9,90 BGN per-month
Mobitel subscribers can download and sync music to their mobile phones from
the PC. They can also download through WAP or Web stores, or from native apps
residing on their handsets.

"Mobiltel is the market leader in Bulgaria-with 50% marketshare-and one
of the most successful operators in Europe," said Andreas Spechtler, managing
director, technology products and services, EMEA, RealNetworks. "We believe
that we can help them unlock their potential to grow their mobile music
subscriber base with our platform, and look forward to the opportunity to
prove that."

Real also powers the music services that make mobile music available to
hundreds of millions of subscribers in Europe and beyond, including mobilkom
austria group's A1 in Austria and Si.Mobil in Slovenia; SFR in France; and
Vodafone music stores in 9 countries, including the United Kingdom, Ireland,
Portugal, Germany, Italy, Greece, The Netherlands, Romania and Spain.

hosts the technologies that enable subscribers to discover, download and
listen to music on their mobile device and personal computer. Real's music
service is now deployed with 15 communications service providers in 15
