Jay-Z was in Silicon Valley yesterday and stopped at Facebook HQ.

Jay-Z and Mark Zuckerberg gave some words of encouragement to the staff members of Facebook.

I not sure why he was in SV but, his new video called "Picasso Baby" will be featured first on HBO August 2, 2013 and then hit the other networks at a later date.

I wonder what kind of deal Jay-Z worked out with HBO and Facebook.
