Washington, Nov. 2 : Two of the web giants, Facebook and Google have reportedly slowed down on their acquisition spree of start-ups in the third quarter.

Both the companies have been active acquirers in the last few years, with the exception of the third quarter this year.

According to AllThingsD, Facebook spent 246 million dollars buying companies in the first six months of 2013 but spent only 14 million dollars in the next three months.

Google acquired Waze for 1 billion dollars and bought 15 other companies for 344 million dollars in the first half of 2013, but spent only 25 million dollars on five purchases in Q3.

The report said that the reason could be that both the companies have concluded that the startup shelves have been pretty picked-over, and there's not a lot else they need to buy. (ANI)
