Announced on 22 January 2019,
Wikimedia Foundation is partnering with Google on a set of initiatives to support a shared commitment of making information more accessible to more people around the world.
Through these partnerships, Google and Wikimedia will be working together to create new and expanded programs to empower editors to create local language content on Wikipedia, as well as developing improved translation tools. To strengthen and support Wikipedia and its mission for generations to come, Google.org will also be contributing $1.1 million to the Wikimedia Foundation and $2 million to the Wikimedia Endowment
