One novel idea implemented by Google is allowing its engineers to spend twenty percent of their time on projects of personal interest. This engagement in personal pursuits has led to the development of some of the corporation's most well-known products and services. AdWords, the advertisement program for Google, was a result of this policy. Google's Gmail, which offers users one gigabyte of storage for email, and Google News, which allows searchers to exclusively search news publications, were also products of this approach.
