YouTube CEO Susan Wojcicki has announced she's stepping down from the helm of the streaming video service. Wojcicki, who joined Alphabet nearly 25 years ago, said she's starting "a new chapter focused on my family, health and personal projects I'm passionate about."
Wojcicki has been involved with Google practically since the beginning. The company's founders, Larry Page and Sergey Brin, set up office in her parents' garage soon after they incorporated Google in 1998. Wojcicki became Google's first marketing manager the following year.
Among other things, she played a role in the earliest Google Doodles, co-created Google Image Search and was the first product manager of AdSense (one of Google's key advertising programs). In 2006, she encouraged Google to buy YouTube, which debuted a year earlier. Eight years later, Wojcicki took over YouTube and became one of the few women to run a major tech company.
