Google I/O 2013 Rumors: Google Play for Education

Google Play for Education is basically a clone of the Google Play store curated specifically with students and educators in mind. The store will launch in the fall and in addition to apps, it will offer textbooks and educational videos via YouTube.

"It's built from the ground up to meet the unique needs of educators," said Yerga.

Google I/O 2013 Rumors: Google +

One of the biggest announcements so far has been a fairly significant overhaul of Google+ which goes live today. The changes include a new multicolumn design and the addition of hashtags to search for content.

"Today we're introducing 41 new features across Google+," Vic Gundotra, senior vice president, of engineering for Google told the audience.

"It's very easy to see a long list of things shared with you, like a never ending newspaper. But it's nearly impossible to go deeper on a topic or interest you have. We think we can fix that," Gundotra said.
