Google Spends Couch Cushion Money on Acquisitions

Apparently Google spent “only” a quarter-billion dollars in acquisitions in the first nine months of 2015. “By comparison, in the first nine months of 2014, Google spent $1.1 billion on non-named acquisitions, plus $2.5 billion on smart-appliance maker Nest, $517 million on Dropcam, and $478 million on satellite company Skybox Imaging.” Saving up for Twitter?
