Behind the Tube

A billion people watch zillions of hours of YouTube video on devices all over the world. Underneath the hood, the magic that makes YouTube isn’t really magic at all—it’s serious engineering at unparalleled scale.

To bring you closer to the people and projects that make YouTube tick, we’re launching the YouTube Engineering and Developers Blog. About once a month, expect to see behind-the-scenes explanations, tools and tips for developers, and explanations of the most fundamental and interesting technical challenges at YouTube.

We look forward to hearing what you think about these topics, so please let us know in the comments or with a video!
