Google's Design Journey, A Great BBC Video
Google has gone from a 90s style web portal to an all encompassing ecosystem and along the way, it gained a focus for making products beautiful.
The video shows the history of Google, the turning point with Larry Page, how Google Now was developed, and actual footage of the design process and prototype designs of Google Now. It also shows Google's weak points in design and where it will have to go to improve design in the future.
It's a great video. You all should check it out.
