The World: New York - Google and MySpace link up and target Facebook

Google and MySpace are joining forces to create a social platform to rival Facebook's popular F8 platform.

The fierce rivals have come together to provide more intense competition for Facebook which, although smaller than MySpace, has captured a lot of attention for its latest move.

In May, Facebook opened up its platform to developers, allowing them to create applications and exploit them through advertising and e-commerce.

Experts say it is a significant move for marketers with their own applications, which they will be able to build for Facebook, and for a sizable amount of the web's social traffic.

Marc Andreessen, the co-founder of Ning, which allows clients to create their own social networking sites, said it would offer access to a huge new pool of users.
