“Greystripe’s rich media ads performed extremely well for us,” said Michelle Mayorga, Mobile Director at Rock the Vote, a Greystripe advertiser. “Advertising in the iPhone with highly engaging ads was perfect for our mission to build the political power of young people because the iPhone reaches a highly targeted demographic.”

“Greystripe is looking to address the lack of advertising standardization in mobile by committing to IAB online formats,” said Michael Chang, CEO and Co-founder of Greystripe. “We have made it easy for advertisers by removing barriers to execution. Brands like Jeep, RadioShack, New Line Cinema, Rock the Vote and Yahoo! have seen strong results.”

To launch the partnership, Sega and Greystripe are launching three popular mobile games:

• Sonic Jump – Go vertical with Sonic the Hedgehog. Play through familiar fast-paced action with an addictive new style as Sonic jumps from platform to platform in a race to stop the evil Dr. Eggman.
• Afterburner II – A classic Sega arcade favorite, players can use their mobile phones to jump into the cockpit of a fighter jet and combat swarms of supersonic enemy fighters.
• Golden Axe – In the epic “side-scrolling beat ‘em up” Golden Axe, choose one of three powerful heroes to embark on an adventure to save the land of Yuria from the evil forces of Death Adder!

“Sega has selected to be a part of the Greystripe’s distribution network of sites as it opens up the category to a whole new market of consumers,” said Linda Chaplin, VP of Mobile at Sega. “The ‘free games’ proposition allows consumers to try mobile games without risk and we’re confident that our brands and commitment to quality will convince consumers to stay and continue gaming on their mobile phones.”

Greystripe’s AdWRAP technology enables advertisements to be wrapped directly with mobile games and applications without any complex coding and development for the content owner. AdWRAP provides game publishers, Web and mobile media portals, and carriers with an additional source of revenue, while simultaneously building customer retention and loyalty.
