One of the biggest acquisitions to happen so far in 2012 was Facebook's purchasing of Instagram for $1 billion in cash and stock. The move, which was Facebook's largest acquisition ever, was seen by some as genius and by other as ridiculous. The craziest part of the deal, however, was not the price, but the way in which it was done. According to the Wall Street Journal, Zuckerberg completed the billion-dollar deal in three days from his Palo Alto home without consulting with, or even telling, the Facebook board. Thanks to Zuck's 57% stake in the company, he can do such things without any repercussions, but for a company as large as Facebook, and one that's on pace to go public, moves like that are seen as unprofessional.
