As of December 2015, StatCounter estimates that Google Chrome has a 58% worldwide usage share of web browsers as a desktop browser.[15] It is also the most popular browser for smartphones, and combined across all platforms at about 45%. Its success has led to Google expanding the 'Chrome' brand name on various other products such as the Chromecast.
Google releases the majority of Chrome's source code as an open-source project Chromium.[16][17] A notable component that is not open source is their version of the built-in Adobe Flash Player, called Pepper Flash Player.
