The MobilKod service (www.mobilkod.com.tr) offers a free service
that allows marketers to create Tags. These 2-D bar codes can be placed on
objects and in printed materials, and, when scanned with the free mobile
application (available at gettag.mobi/tr), they unlock an interactive
mobile experience provided by the brand or advertiser, such as a video, photo
slideshow or mobile website. With MobilKod, marketers can create and measure
the effectiveness of campaigns that use Tags to create holistic brand
experiences by connecting their products and materials in the physical world
to information and interactive content in the digital world.

"As an established innovator in mobile marketing, our mission is to
integrate mobile channels into the marketing mix for 360-degree marketing, as
well as create additional revenues and expand mobile marketing through
interactive experiences and advertising applications," said Sureyya Ciliv,
CEO of Turkcell. "In order to do that, we aim to transform mobile media into
a highly responsive, measurable and interactive channel. Enterprises can use
this channel to reach existing and potential customers while measuring the
rate of return from their investments via detailed reports and analyses."

Turkcell is investing in innovative services and products, such as
location-based services, augmented reality solutions, display advertising,
conceptual branded ad packages, mobile TV advertising, and video advertising
for companies and brands. MobilKod is a new service to expand this product
portfolio and provides the critical ability for brands to create and measure
interactive campaigns that connect their products and services to convenient,
on-the-go experiences for consumers.

The MobilKod Tag Reader (www.mobilkod.com.tr) is available in
Turkey and is available for free on all supported devices, including Android,
iPhone, BlackBerry, J2ME, Symbian and Windows Mobile devices by visiting
gettag.mobi/tr.

"We're excited to have Turkcell as our first mobile operator partner to
extend the Microsoft Tag platform and offer additional value to brands and
marketing partners," said Brian Fleisher, senior director, product management
and business development for Microsoft Tag at Microsoft Corp. "Microsoft Tag
offers a flexible mobile marketing solution, and, combined with the
