RealNetworks Showcases Software and Services Designed to Attract Mobile Subscribers, and Increase Retention and ARPU at Mobile World Congress

Mobile entertainment offerings help operators deliver and manage mobile music, video and photos across multiple platforms and devices

BARCELONA, Spain and SEATTLE, February 14, 2011 - Mobile World Congress — This week, RealNetworks(R), Inc.
(realnetworks.com/index.aspx) (Nasdaq: RNWK), the media software and
services company, will showcase offerings aimed at increasing and retaining
mobile subscribers by speeding up the development of powerful mobile
services, boosting demand for existing offerings and enabling mobile
operators to offer unique consumer services.

Participating in GSMA Mobile World Congress in Barcelona, the company
will demonstrate a variety of SaaS applications and consumer services in
private meetings with mobile operators, OEM's and mobile application
developers. These services will include Real(R)'s industry-leading ringback
tone (RBT) service, music on demand (MOD) service and advanced video
technologies for mobile operators. Additionally, the company will showcase
technologies that make it faster and easier for operators to develop and
deploy video to mobile handsets. Highlights will include:

Unifi(TM) personal media cloud service
(realnetworks.com/pressroom/releases/2011/realnetworks-previews-unifi-at-ces2011.aspx):
New service aims to encourage smartphone and data plan upgrades

Previewed at the 2011 Consumer Electronics Show and slated for
availability in the first half of 2011, Unifi allows consumers to easily
find, access and enjoy the digital media they own. RealNetworks is working
with mobile operators and other partners worldwide to bring the new Unifi
personal media cloud service
(realnetworks.com/pressroom/releases/2011/realnetworks-previews-unifi-at-ces2011.aspx)
to consumers' PCs, tablets and smartphones-regardless of platform or device.

If offered by their mobile operator, consumers will have the option to
add Unifi to their monthly mobile service on a single bill. Unifi increases
consumer engagement with mobile media by enabling access to photos, music,
playlists and videos from any Internet-connected device. In this way, Unifi
can encourage smartphone and data plan upgrades and increase ARPU.

RealNetworks announced today that Vodafone Germany will be the first
mobile operator to offer Unifi
(realnetworks.com/pressroom/releases/2011_releases.aspx) to its
subscribers.

Ringback Tone Open Gateway
(realnetworks.com/products-services/entertainment/rbt_pers.aspx) :
Off-deck promotion of RBTs increases awareness and subscriptions

RealNetworks' long history in providing ringback tone services
(realnetworks.com/products-services/entertainment/rbt_pers.aspx) has
shown that adoption rates rise directly with increased marketing and
promotion. One proven method to raise marketing activity levels is through
third-party, off-deck promotion of RBTs through channel partners' music
storefronts, music apps and social networking sites, increasing RBT
subscription rates and RBT usage
(realnetworks.com/products-services/entertainment/rbt_pers.aspx) for
all mobile operators.

Expected to be available in Q3 of 2011, RealNetworks' RBT Open Gateway
makes multiple operators' RBT content available to all subscribers and
simplifies the end-user experience. It also makes it easy for mobile
operators and third parties - like digital music providers, bloggers, music
labels and artists - to promote RBT content. Whether on a mobile device or on
the Web, the process is simple. When a mobile subscriber selects an RBT and
sends the corresponding music code to the RealNetworks RBT Open Gateway, the
RBT is provided through their mobile operator's RBT system.

For artists and music labels, the RBT Open Gateway provides an easy way
to market their own RBT content to consumers across multiple mobile operators
and through a variety of channels, from artist fan sites to CD covers. An RBT
widget builder, a Facebook application and a mobile application make it
possible for site owners to promote and feature RBTs on a specific web or WAP
page.

As exposure and awareness of ringback tones continue to grow, mobile
operators could expect an increase in subscription and RBT sales driven by
new channel partners.

Helix Rich Media Client
(realnetworks.com/products-services/helix-rich-media-client.aspx) :
Develop mobile TV interface once, deploy broadly

Available now, RealNetworks' Helix (R)
(realnetworks.com/helixplatform.aspx) Rich Media Client gives
mobile operators the ability to design a single mobile TV and VOD interface
that can then be automatically deployed on numerous mobile video applications
– on any smartphone and on any platform, with the same look and feel. This
allows mobile operators to deliver the same mobile TV application
functionality with a native experience instantly across all smartphones,
including iPhone, Android, Windows Mobile, Symbian and Blackberry, as well as
to Java-enabled feature phones. Customers can focus on building a rich,
dynamic, custom experience and create rapid business applications or use
RealNetworks' mobile TV and VOD mobile application template.

HTTP Live Streaming for Android
(realnetworks.com/pressroom/releases/2010/RealPlayer-for-Mobile-Delivers-HTTP-Live-Content-to-Android.aspx):
Allows content built for iPad and iPhone to be played on Android devices

RealPlayer(R) for Mobile includes HTTP Live Streaming for Android. The
new feature takes content created for Apple's HTTP Live streaming protocol
and makes it playable on Android devices. By adopting this new feature of
RealPlayer for Mobile, handset, tablet and CE OEMs can easily expand the
amount of content played by their Android devices. Video content encoded for
HTTP Live will play seamlessly on Android devices, so content creators can
encode once and reach both Apple and Android users.

RealNetworks (www.realnetworks.com/index.aspx) will be
demonstrating the Unifi service by appointment at Mobile World Congress in a
hospitality suite in The Fira, Hall 4, Level 0, Monday, 14 February to
Thursday, 17 February. To set up a meeting, please see contact info below.
