Alphabet maintains the largest online index of websites accessible through automated search technology. It generates revenue through online advertising, cloud services, and consumer devices. Google is an operating segment of Alphabet. The company was founded in 1998 by Sergey Brin and Larry Page and went public in 2004. Google's AdWords is an auction-based program that lets businesses display ads along with particular search results. Google's AdSense program enables websites in the company's network to serve targeted ads, based on search terms or web content, from AdWords advertisers. Most of the revenue generated through AdSense is shared with network partners. In addition, Alphabet owns YouTube.com, the web-based video site. It has expanded into mobile telephony with its Android smartphone operating system, into cloud services, and most recently, into autonomous driving. About 52% of Alphabet's revenue is generated outside the U.S.

Alphabet is a holding company that wholly owns internet giant Google. The California-based company derives slightly less than 90% of its revenue from Google services, the vast majority of which is advertising sales. Alongside online ads, Google services houses sales stemming from Google’s subscription services (YouTube TV and YouTube Music, among others), platforms (sales and in-app purchases on Play Store), and devices (Chromebooks, Pixel smartphones, and smart home products such as Chromecast). Google’s cloud computing platform accounts for roughly 10% of Alphabet’s revenue. The firm’s investments in up-and-coming technologies such as self-driving cars (Waymo), health (Verily), and internet access (Google Fiber) make up the rest.
