The Wikimedia Foundation has received the largest donation in the current fundraising campaign, which was launched this week. Half a million dollars came from the charitable fund of Brin Wojcicki Foundation, created by Sergey Brin and his wife Anne Wojcicki.
The money will be a significant contribution to the common fund. The grants and donations are the main source of existence for Wikipedia and other Wikimedia projects. The money comes from the users, they usually donate about 5-10 euro. Fortunately, some people can part with a greater amount of money.
