The timeline shows Google's quarterly revenues since 2008. In the fourth quarter of 2015, Google's revenue amounted to 21.18 billion U.S. dollars, up from 18.53 billion U.S. dollars in the preceding quarter. Google's main revenue source is advertising through Google sites and its network.
As expected, Google’s revenue continues to increase each year. In the third quarter of 2015, the company’s revenue totaled 18,675 billion U.S. dollars, the company’s best quarter of the year, for a cumulative total of 53,659 billion so far for 2015. The company is well on its way to surpassing its 2014 annual revenue of 66 billion. The majority of Google’s revenue comes from advertising through Google owned and operated properties such as Google Search, Google Maps and more.
In 2014, almost 70 percent of its revenue was generated on Google’s Sites, while around 20 percent came from advertising on Google’s network member’s websites and the remaining 10 percent came from licensing and other revenues. The revenues generated from Google’s network member’ websites include revenue from ads served through advertising programs such as AdSense for AdSearch for example. Other revenue include digital content products and apps sold through Google’s Play digital content distribution platform, as well as hardware include Chromecast devices and smartphones. With revenues projected to surpass 11 billion U.S. dollars in 2018, Google Play is an increasingly important contributor to Google’s bottom line, especially as smartphones sales and Google’s Android platform’s global market share increase. Geographically, the biggest single country share of Google’s revenue comes from the United States, but 47 percent of revenue come from the rest of the world and 10 percent from the United Kingdom.
