Google is widely recognized the world leader in web search, and a forerunner in many other major online services, such as streaming video, e-mail, and cloud storage. The bulk of their business is in software, but they've popularized digital eyewear thanks to their Glass headset, which is still in a public testing phase. Though Google's role in the hardware business is still young, their acquisition of Nest shows a deeper interest in becoming a major part of connected homes.
Google's Android OS has been around for a number of years now, quickly becoming one of the most popular mobile OS platforms in the world. Android can now be found on millions of devices across the globe — not only smartphones and tablets — but now also appliances, wearables and other connected devices. Google introduced Android Wear in 2014 as a wearable version if their Android OS, which will be used in many devices — namely smartwatches. Companies like Motorola, LG and Samsung have all announced that they will offer Android Wear devices, taking Google one step further into the connected space.
Google currently employees nearly 50k people and is headquartered in Mountain View, California. Googles subsidiaries include AdMob, DoubleClick, On2 Technologies, Picnik, YouTube, Zagat, Waze, Blogger, SlickLogin, Boston Dynamics, Bump, Nest Labs, DeepMind Technologies, WIMM One and VirusTotal.
