Together we've covered topics including how autocomplete works, how Google protects its users, how Search determines what ads a user sees, and how it’s able to quickly surface information during a crisis.

The brief for each film was often just a user question Google wanted to answer—like “If Google has all this data about me, what are they doing to keep it safe?”

Each video was a balancing act. Provide enough information to help someone understand, but not so much detail they become confused. Give a complete explanation, but keep it under two minutes. We also wanted to create a visual story that’s compelling to watch, but doesn’t feel like it’s glossing over a complex problem.

Now after tens of millions of views on YouTube, the How Search Works video series has been a huge step in Google’s efforts to be a more transparent organization, with millions of users finding simple answers to some very complex questions.
