Google

Google is arguable the most popular search engine in the world. There are competitors but you don't hear anyone "say Bing or Yahoo it". Without search engines it would be a lot more difficult to research and find answers to questions. Many times researching a simple question you can find answers quickly but it often takes a lot longer when searching using Yahoo or Bing. Google isn't just a great search engine though, Google has released free software. Google has released Google earth so you can see a satellite view from of the earth and be able to zoom in and see your house. Google also released Google sketch up which is great tools if you want create 3D models of buildings. Google is also has created a mobile phone operating system called android. Google is a rapidly growing company and it will be interesting what Google's next product or website will be.
