Google Launches Own App Store, Apps Marketplace
While it won't be catching up with the Apple App Store any time soon, the Google Apps Marketplace launched with more than 50 apps from companies including Intuit and Atlassian, with others coming soon from companies such as NetSuite and SuccessFactors.
Using Google's API's, it's a simple process for developers to integrate any application into Google Apps. It costs $100 for developers to sign up for the developer program, which provides them with access to Google tools and API's, and enables them to sell their applications to businesses using Google Apps.
Developers can view all the details by visiting Google's Developer Programs site.
