Everyone's favourite search engine Google turns 20 today. Google began as a research project for two PhD students Larry Page and Sergey Brin in 1996. The two registered the domain name for it in September 1997. And in 1998, the two finally set the foundation stone for what went on to become the biggest search engine in the world. It's hard to imagine a life without Google, especially for millennials and post-millennials who turn to it for everything from looking for the perfect pizza place to finding answers to life's most vexing questions.
