Each year from \~mid-October through the end of December, the Tor Project runs its year-end fundraising campaign (aka "YEC"). This is the time during which we raise the most money per year from individual donors. A key strategy in this campaign is a branded takeover of about:tor (desktop + mobile) that includes the year-end campaign "mini brand," new assets, a fundraising message, and a donate button.
