Google is an United States based multinational technology company that specializes in Internet-related services and products, which include online advertising technologies, a search engine, cloud computing, software, and hardware. It is considered one of the Big Four technology companies alongside Amazon, Apple, and Microsoft.
Google was founded in September 1998 by Larry Page and Sergey Brin while they were Ph.D. students at Stanford University in California.
The company's rapid growth since incorporation has triggered a chain of products, acquisitions, and partnerships beyond Google's core search engine (Google Search).
Google Search, also referred to as Google Web Search or simply Google, is a web search engine developed by Google. It is the most used search engine on the World Wide Web across all platforms, with 92.62% market share as of June 2019, handling more than 5.4 billion searches each day.
The order of search results returned by Google is based, in part, on a priority rank system called "PageRank".
Google Search also provides many different options for customized search, using symbols to include, exclude, specify or require certain search behavior, and offers specialized interactive experiences, such as flight status and package tracking, weather forecasts, currency, unit and time conversions, word definitions, and more.
