The figures below show how much Facebook, Google, Microsoft and Yahoo have spent on tech acquisitions – in billions of dollars. Via whoishostingthis.com There are two clear leaders in the race: Facebook (in blue), and Google (in red). Via whoishostingthis.com Both companies made relatively tentative deals in 2010. Via whoishostingthis.com At present Facebook owns 46 companies, and Google 146. Via whoishostingthis.com What we're witnessing now, however, is essentially a tech arms race. Via whoishostingthis.com None of these acquisitions have allowed the companies to expand beyond their core businesses yet. Via whoishostingthis.com Facebook has less wiggle room for risks than Google, which can afford to lose bets (as it did on Motorola). Via whoishostingthis.com The history of technology firms is that they can spectacularly crash the moment they fail to stay on top of the market. Both Google's Larry Page and Facebook's Mark Zuckerberg are trying their best to make sure it isn't them that loses the war. Design by Neomam for Who Is Hosting This.
