The last few weeks have not brought good news for Facebook. Just as the company introduced a widely-hyped yet underperforming IPO, the efficacy of Facebook's advertising model came into question when GM announced that it would pull its primary ad campaign because it was not bringing in results.

Facebook has very recently revealed its potentially one of the biggest acquisition of popular photo sharing app Instagram. The deal has been closed for a whopping $1 billion, in a combination of cash and stock of Facebook. The entire deal will be closed by end of this quarter.

"For years, we've focused on building the best experience for sharing photos with your friends and family. Now, we'll be able to work even more closely with the Instagram team to also offer the best experiences for sharing beautiful mobile photos with people based on your interests." shares Facebook's CEO Mark Zuckerberg.

Facebook in itself is undeniably one of the largest photo-sharing platform. Instagram on the other hand has reached 27 million users on iOS alone, and with its recent Android launch, it is expected to have a much larger number of users. But in spite of Instagram's ever-growing popularity, it is out of Facebook's character and culture to go ahead and acquire a booming service.
