Wojcicki has been working hard to grow the $9 billion online video site despite growing competition from Facebook, Amazon, Netflix, and Snapchat. She has added live streaming, new ad formats, and virtual-reality videos to the site, which counts over 1 billion users worldwide. She has also been boosting the amount of premium original content, recently acquiring the rights to the TV drama Step Up. Now the company hopes to bring in more dollars through ad-free subscription services that also provide streaming music.
