Internet companies generate their revenue through various means. For instance, Google uses its advertisement services, such as Google AdWords – which takes advantage of Google searches and appears as small advertisements next to search results – and Google AdSense, which generates advertisements based on a user's search history and location, among others. Advertisements based on AdSense appear across Google-owned sites, including YouTube and Google Finance. The online company also profits from the development of Android OS, licensing, and mobile apps, as well as the recent development of hardware such as the Nexus mobile device series and Google Glass. In 2022, Google’s total revenue amounted to 279.8 billion U.S. dollars.
