Facebook's new aquisition

If you thought that Google + would slow down the facebook's expansion, then perhaps you might be wrong.Social networking giant Facebook has bought a digital publishing company Push Pop Press that develops technology to help make interactive books optimised for iPad and other Apple devices.

"We're thrilled to confirm that we've acquired Push Pop Press, a startup whose groundbreaking software changes the way people publish and consume digital content," Xinhua quoted Facebook as saying in a statement.

Push Pop Press was co-founded by Mike Matas and Kimon Tsinteris - both former Apple employees.

It had also teamed up with former US vice president Al Gore to create a digital version of his book "Our Choice".

"Although Facebook isn't planning to start publishing digital books, the ideas and technology behind Push Pop Press will be integrated with Facebook, giving people even richer ways to share their stories," Push Pop Press said in a statement.

"With millions of people publishing to Facebook each day, we think it's going to be a great home for Push Pop Press," it said.

Financial terms of the deal were not disclosed by the two companies.
