Google Contributor was a program run by Google that allowed users in the Google Network of content sites to view the websites without any advertisements that are administered, sorted, and maintained by Google. The program was launched publicly with prominent websites, like The Onion and Mashable among others, to test this service. After November 2015, the program opened up to any publisher who displayed ads on their websites through Google AdSense without requiring any sign-on from publishers. After November 2015, the program was available to everyone in the United States. Google Contributor stopped accepting new registrations after December 2016 in preparation for a new version launch in early 2017. On January 17, Google Contributor was shut down, with the landing page stating "We're launching a new and improved Contributor in early 2017!" In June 2017, the new Google Contributor was launched, but was shut down again. Some of the pages for Google Contributor still exist, but there is no way to sign up nor to log in, and the link for site owner help goes to a generic Google help page. In August 2020, some websites were available for Google Contributors, such as MTL Blog.
