Is Facebook turning from Social Network to Sponsored Network?

Today Morning, I opened up the facebook ! On my Wall's right hand side was 'Sponsored' link and 'Sponsored Pages' - around 4-5 Sponsored links. Fine not a problem!!

Then I clicked on Friend's photo to comment on it - WOW another 'Sponsored Stories'.. below the Photo Comments they have put sponsored stories.

What next?? I assume they will promote 'Sponsored Friend' !! Get life Facebook.
