They've been pretty hard at work to offer services that will let them wean themselves off of Google money. This is how much of their income came from search royalties yearly according to their independent auditor reports
[^a]: this was a weird year where their "other" income got a massive one-time boost. I'm not sure what happened. Did they get a $338m grant? If you take that number out (which is normally at or near zero) the percentage is around 91%
