Android is a mobile operating system developed by Google based on a modified version 
	of Linux and other open source software. It was designed primarily for touchscreen 
	mobile devices such as tablets and smartphones. Google has also developed Android TV 
	for televisions, Android Auto for cars, and Wear OS for wearables. Variants of the 
	Android OS are also used on PCs, game consoles, digital cameras, and other electronics.

	Initially developed/founded in Oct. 2003 by Android Inc., which Google bought in 2005, Android 
	was unveiled in 2007, with the first commercial Android device launched in September 2008. 

	On August 22, 2019, it was announced that Android "Q" would officially be branded as Android 10, 
	ending the historic practice of naming major versions after desserts. Google stated that these 
	names were not "inclusive" to international users (due either to the aforementioned foods not 
	being internationally known, or being difficult to pronounce in some languages).

	The current version as of Sep. 3, 2019 is Android 10. The core Android source code is known 
	as Android Open Source Project (AOSP), which is primarily licensed under the Apache License.

	Android is also associated with other software developed by Google, called 'Google Mobile Services' 
	(GMS), that frequently come pre-installed on devices. This includes core apps such as Gmail, the 
	application store/digital distribution platform Google Play and associated Google Play Services 
	development platform. This usually includes the Google Chrome web browser and Google Search app. 
	These apps are licensed by manufacturers of Android devices certified under standards imposed by 
	Google, but AOSP has been used as the basis of competing Android ecosystems such as Amazon.com's 
	Fire OS, which use their own equivalents to 'Google Mobile Services' (GMS).

	Android is the most used OS worldwide on smartphones since 2011 and tablets since 2013. 
	As of May 2017, Android has over two billion monthly active users, the largest installed 
	base of any operating system. As of December 2018, the Google Play store features over 
	2.6 million apps for use with Android.
