MySpace and Google have announced they are collaborating in a deal that could change the landscape of social networking.

MySpace has agreed to join OpenSocial, a Google’s platform that allows developers to build applications that will work on any platform. Besides MySpace, other sits like Bebo, LinkedIn and Orkut are members of OpenSocial. The participation of MySpace, with 200 million users, will encourage more programmers to develop applications on OpenSocial.

According to Google, they have reached out to everyone in the social networking industry to join OpenSocial and it indicated that included Facebook.

Meanwhile, Facebook is still sitting at the sideline waiting to see further development on OpenSocial. Since opening up its platform the programmers, Facebook has tens of thousand programmers developing applications for Facebook.

Recently, Facebook sold 1.6% stake to Microsoft for US$240million. MySpace is owned by Rupert Murdoch’s News Corp.

MySpace is opening up its platform to allow programmers to write applications to run this famous social networking site, announced Chris DeWolfe at the Web 2.0 conference in San Francisco.  MySpace is following the footstep of Facebook and Apple in opening up its platform to harness the pool of programmers to develop applications to enhance the capabilities of MySpace.

MySpace with 110 million users is almost double that of Facebook but it does not command the same value like Facebook. Mark Zuckerberg, CEO of Facebook, announced that Facebook is expected to wrap up financing that could value up to $15 billion.

DeWolfe announced that MySpace will start testing its platform with new applications, developed with tools supplied by MySpace, with about 2 million users in December. MySpace will allow outside developers to sell their ads. This is the biggest news for developers in the booming market for add-on software.

Intermix Media, the owner of Myspace, was acquired by Ruper Murdoch’s News Corp for US$580 million in 2005.
