Today Greystripe, a mobile advertising network, announced ad network support for Nokia's Ovi Store. Greystripe enables developers to automatically add pre-load and exit 'screen' rich media adverts to their games applications via a self-service web portal. This should result in an increased number of ad-supported (free) games and applications in the Ovi Store. Additionally Greystripe is migrating 1,200 Gamejump.com Java titles into Ovi Store.

Greystripe say that its Java and Symbian applications are currently downloaded roughly 250,000 times a day. By adding Ovi Store support Greystripe should be able to extend its reach and increase the downloads of Greystripe enabled ad-supported applications.

Ovi Store passed the 1 million downloads a day towards the end of the fourth quarter of 2009 (as noted in Nokia's Q4 results) and is seeing strong month to month growth.

GameJump.com games are generally Java games from a few years ago. There are some good titles available, but many of the games look some what dated. However they are a good fit for some of the older devices in Nokia's device portfolio (e.g. N73) and Series 40 phones. It is worth remembering that Ovi Store support has now been added to most of Nokia's S60 3rd Edition and above phones.

Greystripe already supports the Android and iPhone platform and is likely to be the first of many ad service companies to add Ovi Store support to its offerings.

From the press release:

Greystripe has created an automated and completely self service web-based portal for developers to ad enable their Java/Symbian apps. Using Greystripe’s proprietary technology, developers can upload all of their fully developed mobile app ports, each file supporting an individual phone model, while the ad client is automatically merged with their application. Developers offer their apps for free to consumers and monetize using Greystripe’s ad network by displaying pre- and post-roll full-screen ads.

"We are excited to be able to offer the most complete set of mobile in-app ad platforms to our brand advertisers,” said Michael Chang, CEO for Greystripe. “This announcement reinforces one of our main objectives as a network, to reach the broadest audience possible, in addition to our iPhone and Android users."

"Greystripe’s advertising solution makes it super easy for us to ad enable fully completed and ported mobile apps and then load them into Ovi for broad distribution," said Dmitriy Surchenov, Business Development Manager at United Fun Traders Ltd., developer of Farm Frenzy.
