https://en.wikipedia.org/wiki/Google_Contributor
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 started 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.
Since November 2015, the program was available for everyone in the United States. Google Contributor stopped accepting new registrations after December 2016 in preparation for a new version launch in early 2017.[1] On January 17th, Google Contributor was shut down. As of January 17, 2017 8:40 AM no replacement had been announced.
